# Class Ext.form.FormPanel

Package: | Ext.form
Defined In: | Form.js
Class: | FormPanel
Extends: | Panel

Standard form container.

Layout

By default, FormPanel is configured with `layout:'form'` to use an Ext.layout.FormLayout layout manager, which styles and renders fields and labels correctly. When nesting additional Containers within a FormPanel, you should ensure that any descendant Containers which host input Fields use the Ext.layout.FormLayout layout manager.

BasicForm

Although not listed as configuration options of FormPanel, the FormPanel class accepts all of the config options required to configure its internal Ext.form.BasicForm for:

- file uploads
- functionality for loading, validating and submitting the form

Note: If subclassing FormPanel, any configuration options for the BasicForm must be applied to the `initialConfig` property of the FormPanel. Applying BasicForm configuration settings to `this` will not affect the BasicForm's configuration.

Form Validation

For information on form validation see the following:

- Ext.form.TextField
- Ext.form.VTypes
- BasicForm.doAction clientValidation notes
- `monitorValid`

Form Submission

By default, Ext Forms are submitted through Ajax, using Ext.form.Action. To enable normal browser submission of the BasicForm contained in this FormPanel, see the `standardSubmit` option.

A string component id or the numeric index of the component that should be initially activated within the container's layout on render. For example, activeItem: 'item-1' or activeItem: 0 (index 0 = the first item in the container's collection). activeItem only applies to layout styles that can display items one at a time (like Ext.layout.AccordionLayout, Ext.layout.CardLayout and Ext.layout.FitLayout). Related to Ext.layout.ContainerLayout.activeItem. | Container

| applyTo : Mixed The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document ... The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document that specifies some panel-specific structural markup. When `applyTo` is used, constituent parts of the panel can be specified by CSS class name within the main element, and the panel will automatically create those components from that markup. Any required components not specified in the markup will be autogenerated if necessary. The following class names are supported (baseCls will be replaced by baseCls): baseCls + '-header' baseCls + '-header-text' baseCls + '-bwrap' baseCls + '-tbar' baseCls + '-body' baseCls + '-bbar' baseCls + '-footer' Using this config, a call to render() is not required. If applyTo is specified, any value passed for renderTo will be ignored and the target element's parent node will automatically be used as the panel's container. | Panel
| autoDestroy : Boolean If true the container will automatically destroy any contained component that is removed from it, else destruction mu... If true the container will automatically destroy any contained component that is removed from it, else destruction must be handled manually (defaults to true). | Container
| autoHeight : Boolean true to use height:'auto', false to use fixed height (defaults to false). Note: Setting autoHeight: true means that t... `true` to use height:'auto', `false` to use fixed height (defaults to `false`). Note: Setting `autoHeight: true` means that the browser will manage the panel's height based on its contents, and that Ext will not manage it at all. If the panel is within a layout that manages dimensions (`fit`, `border`, etc.) then setting `autoHeight: true` can cause issues with scrolling and will not generally work as expected since the panel will take on the height of its contents rather than the height required by the Ext layout. | Panel
| autoLoad : Object/String/Function A valid url spec according to the Updater Ext.Updater.update method. If autoLoad is not null, the panel will attempt ... A valid url spec according to the Updater Ext.Updater.update method. If autoLoad is not null, the panel will attempt to load its contents immediately upon render. The URL will become the default URL for this panel's body element, so it may be refreshed at any time. | Panel
| autoScroll : Boolean true to use overflow:'auto' on the components layout element and show scroll bars automatically when necessary, false... `true` to use overflow:'auto' on the components layout element and show scroll bars automatically when necessary, `false` to clip any overflowing content (defaults to `false`). | BoxComponent
| autoShow : Boolean True if the component should check for hidden classes (e.g. 'x-hidden' or 'x-hide-display') and remove them on render... True if the component should check for hidden classes (e.g. 'x-hidden' or 'x-hide-display') and remove them on render (defaults to false). | Component
| autoWidth : Boolean True to use width:'auto', false to use fixed width (or allow it to be managed by its parent Container's layout manage... True to use width:'auto', false to use fixed width (or allow it to be managed by its parent Container's layout manager. Defaults to false. Note: Although many components inherit this config option, not all will function as expected with a width of 'auto'. Setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all. If the browser is managing the width, be aware that resizes performed by the browser in response to changes within the structure of the Component cannot be detected. Therefore changes to the width might result in elements needing to be synchronized with the new width. For example, where the target element is:
    <div id='grid-container' style='margin-left:25%;width:50%'></div>
A Panel rendered into that target element must listen for browser window resize in order to relay its child items when the browser changes its width:
    var myPanel = new Ext.Panel({
        renderTo: 'grid-container',
        monitorResize: true, // relay on browser resize
        title: 'Panel',
        height: 400,
        autoWidth: true,
        layout: 'hbox',
        layoutConfig: {
            align: 'stretch'
        },
        defaults: {
            flex: 1
        },
        items: [{
            title: 'Box 1',
        }, {
            title: 'Box 2'
        }, {
            title: 'Box 3'
        }],
    });
| BoxComponent
| baseCls : String The base CSS class to apply to this panel's element (defaults to 'x-panel'). Another option available by default is t... The base CSS class to apply to this panel's element (defaults to `'x-panel'`). Another option available by default is to specify `'x-plain'` which strips all styling except for required attributes for Ext layouts to function (e.g. overflow:hidden). See `unstyled` also. | Panel
| bbar : Object/Array The bottom toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button co... The bottom toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button configs to be added to the toolbar. Note that this is not available as a property after render. To access the bottom toolbar after render, use getBottomToolbar. Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree. | Panel

True to display an interior border on the body element of the panel, false to hide it (defaults to true). This only applies when border == true. If border == true and bodyBorder == false, the border will display as a 1px wide inset border, giving the entire body element an inset appearance. | Panel

A DomHelper element specification object may be specified for any Panel Element. By default, the Default element in the table below will be used for the html markup to create a child element with the commensurate Default class name (`baseCls` will be replaced by `baseCls`):

Configuring a Custom element may be used, for example, to force the body Element to use a different form of markup than is created by default. An example of this might be to create a child Panel containing a custom content, such as a header, or forcing centering of all Panel content by having the body be a <center> element:
    new Ext.Panel({
        title: 'Message Title',
        renderTo: Ext.getBody(),
        width: 200, height: 130,
        bodyCfg: {
            tag: 'center',
            cls: 'x-panel-body',  // Default class not applied if Custom element specified
            html: 'Message'
        },
        footerCfg: {
            tag: 'h2',
            cls: 'x-panel-footer',        // same as the Default class
            html: 'footer html'
        },
        footerCssClass: 'custom-footer', // additional css class, see addClass
        footerStyle:    'background-color:red' // see bodyStyle
    });
The example above also explicitly creates a `footer` with custom markup and styling applied. | Panel

When set to true (50 milliseconds) or a number of milliseconds, the layout assigned for this container will buffer the frequency it calculates and does a re-layout of components. This is useful for heavy containers or containers with a large quantity of sub-components for which frequent layout calls would be expensive. Defaults to `50`. | Container

An array of Ext.Buttons or Ext.Button configs used to add buttons to the footer of this FormPanel. Buttons in the footer of a FormPanel may be configured with the option `formBind: true`. This causes the form's valid state monitor task to enable/disable those Buttons depending on the form's valid/invalid state. | FormPanel

The CSS class used to to apply to the special clearing div rendered directly after each form field wrapper to provide field clearing (defaults to `'x-form-clear-left'`). Note: this config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager (e.g. Ext.form.FormPanel or specifying `layout:'form'`) and either a `fieldLabel` is specified or `isFormField=true` is specified. See Ext.layout.FormLayout.fieldTpl also. | Component

Specify an existing HTML element, or the `id` of an existing HTML element to use as the content for this component. Description : This config option is used to take an existing HTML element and place it in the layout element of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content. Notes : The specified HTML element is appended to the layout element of the component after any configured HTML has been inserted, and so the document will not contain this element at the time the render event is fired. The specified HTML element used will not participate in any `layout` scheme that the Component may use. It is just HTML. Layouts operate on child `items`. Add either the `x-hidden` or the `x-hide-display` CSS class to prevent a brief flicker of the content before it is rendered to the panel. | Component

An optional extra CSS class that will be added to this component's container. This can be useful for adding customized styles to the container or any of its children using standard CSS rules. See Ext.layout.ContainerLayout.extraCls also. Note: `ctCls` defaults to `''` except for the following class which assigns a value by default: Box Layout : `'x-box-layout-ct'` To configure the above Class with an extra CSS class append to the default. For example, for BoxLayout (Hbox and Vbox):
    ctCls: 'x-box-layout-ct custom-class'

The default xtype of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component. Defaults to `'panel'`, except Ext.menu.Menu which defaults to `'menuitem'`, and Ext.Toolbar and Ext.ButtonGroup which default to `'button'`. | Container
| defaults : Object|Function This option is a means of applying default settings to all added items whether added through the items config or via ... This option is a means of applying default settings to all added items whether added through the items config or via the add or insert methods. If an added item is a config object, and not an instantiated Component, then the default properties are unconditionally applied. If the added item is an instantiated Component, then the default properties are applied conditionally so as not to override existing properties in the item. If the defaults option is specified as a function, then the function will be called using this Container as the scope (`this` reference) and passing the added item as the first parameter. Any resulting object from that call is then applied to the item as default properties. For example, to automatically apply padding to the body of each of a set of contained Ext.Panel items, you could pass: `defaults: {bodyStyle:'padding:15px'}`. Usage:
    defaults: {               // defaults are applied to items, not the container
        autoScroll:true
    },
    items: [
        {
            xtype: 'panel',   // defaults do not have precedence over
            id: 'panel1',     // options in config objects, so the defaults
            autoScroll: false // will not be applied here, panel1 will be autoScroll:false
        },
        new Ext.Panel({       // defaults do have precedence over options
            id: 'panel2',     // options in components, so the defaults
            autoScroll: false // will be applied here, panel2 will be autoScroll:true.
        })
    ]
| Container

An important note when using the disabled config on panels is that IE will often fail to initialize the disabled mask element correectly if the panel's layout has not yet completed by the time the Panel is disabled during the render process. If you experience this issue, you may need to instead use the afterlayout event to initialize the disabled state:
    new Ext.Panel({
        ...
        listeners: {
            'afterlayout': {
                fn: function(p){
                    p.disable();
                },
                single: true // important, as many layouts can occur
            }
        }
    });

For custom drag/drop implementations, an Ext.Panel.DD conf... `true` to enable dragging of this Panel (defaults to `false`). For custom drag/drop implementations, an Ext.Panel.DD config could also be passed in this config instead of `true`. Ext.Panel.DD is an internal, undocumented class which moves a proxy Element around in place of the Panel's element, but provides no other behaviour during dragging or on drop. It is a subclass of Ext.dd.DragSource, so behaviour may be added by implementing the interface methods of Ext.dd.DragDrop e.g.:
    new Ext.Panel({
        title: 'Drag me',
        x: 100,
        y: 100,
        renderTo: Ext.getBody(),
        floating: true,
        frame: true,
        width: 400,
        height: 200,
        draggable: {
    //      Config option of Ext.Panel.DD class.
    //      It's a floating Panel, so do not show a placeholder proxy in the original position.
            insertProxy: false,

    //      Called for each mousemove event while dragging the DD object.
            onDrag : function(e){
    //          Record the x,y position of the drag proxy so that we can
    //          position the Panel at end of drag.
                var pel = this.proxy.getEl();
                this.x = pel.getLeft(true);
                this.y = pel.getTop(true);

    //          Keep the Shadow aligned if there is one.
                var s = this.panel.getEl().shadow;
                if (s) {
                    s.realign(this.x, this.y, pel.getWidth(), pel.getHeight());
                }
            },

    //      Called on the mouseup event.
            endDrag : function(e){
                this.panel.setPosition(this.x, this.y);
            }
        }
    }).show();

A comma-delimited list of panel elements to initialize when the panel is rendered. Normally, this list will be generated automatically based on the items added to the panel at config time, but sometimes it might be useful to make sure a structural element is rendered even if not specified at config time (for example, you may want to add a button or toolbar dynamically after the panel has been rendered). Adding those elements to this list will allocate the required placeholders in the panel when it is rendered. Valid values are `header` `tbar` (top bar) `body` `bbar` (bottom bar) `footer` Defaults to '`body`'. | Panel

A Toolbar object, a Toolbar config, or an array of Buttons/Button configs, describing a Toolbar to be rendered into this Panel's footer element. After render, the `fbar` property will be an Toolbar instance. If `buttons` are specified, they will supersede the `fbar` configuration property. The Panel's `buttonAlign` configuration affects the layout of these items, for example:
    var w = new Ext.Window({
        height: 250,
        width: 500,
        bbar: new Ext.Toolbar({
            items: [{
                text: 'bbar Left'
            },'->',{
                text: 'bbar Right'
            }]
        }),
        buttonAlign: 'left', // anything but 'center' or 'right' and you can use '-', and '->'
                                      // to control the alignment of fbar items
        fbar: [{
            text: 'fbar Left'
        },'->',{
            text: 'fbar Right'
        }]
    }).show();
Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree. | Panel

The label text to display next to this Component (defaults to ''). Note: this config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager (e.g. Ext.form.FormPanel or specifying `layout:'form'`). Also see `hideLabel` and Ext.layout.FormLayout.fieldTpl. Example use:
    new Ext.FormPanel({
        height: 100,
        renderTo: Ext.getBody(),
        items: [{
            xtype: 'textfield',

Note: this config is only used when this Component is rendered by a Container which has been configured to use a BoxLayout. Each child Component with a `flex` property will be flexed either vertically (by a VBoxLayout) or horizontally (by an HBoxLayout) according to the item's relative `flex` value compared to the sum of all Components with `flex value specified. Any child items that have either a `flex = 0` or `flex = undefined` will not be 'flexed' (the initial size will not be changed).` | BoxComponent

This property is used to configure the underlying Ext.Layer. Acceptable values for this configuration property are: `false` : Default. Display the panel inline where it is rendered. `true` : Float the panel (absolute position it with automatic shimming and shadow). Setting floating to true will create an Ext.Layer for this panel and display the panel at negative offsets so that it is hidden. Since the panel will be absolute positioned, the position must be set explicitly after render (e.g., `myPanel.setPosition(100,100);`). Note: when floating a panel you should always assign a fixed width, otherwise it will be auto width and will expand to fill to the right edge of the viewport. `object` : The specified object will be used as the configuration object for the Ext.Layer that will be created. | Panel

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Instead of using an `id` with Ext.getCmp, use `itemId` with Ext.Container.getComponent which will retrieve `itemId`'s or `id`'s. Since `itemId`'s are an index to the container's internal MixedCollection, the `itemId` is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentMgr which requires a unique `id`.

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once. DOM events from ExtJs Components While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the DataView's `click` event passing the node clicked on. To access DOM events directly from a Component's HTMLElement, listeners must be added to the Element after the Component has been rendered. A plugin can simplify this step:
    // Plugin is configured with a listeners config object.
    // The Component is appended to the argument list of all handler functions.
    Ext.DomObserver = Ext.extend(Object, {
        constructor: function(config) {
            this.listeners = config.listeners ? config.listeners : config;
        },

            for (p in l) {
                if (Ext.isFunction(l[p])) {
                    l[p] = this.createHandler(l[p], c);
                } else {

                }
            }

            // Add the listeners to the Element immediately following the render call
            c.render = c.render.createSequence(function() {
                var e = c.getEl();
                if (e) {
                    e.on(l);
                }
            });
        },

        createHandler: function(fn, c) {

    });

    }
May also be a string containing space-separated, numeric margin values. The order of the sides associated with each value matches the way CSS processes margin values: If there is only one value, it applies to all sides. If there are two values, the top and bottom borders are set to the first value and the right and left are set to the second. If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third. If there are four values, they apply to the top, right, bottom, and left, respectively. Defaults to:

A path specification, relative to the Component's `ownerCt` specifying into which ancestor Container to place a named reference to this Component. The ancestor axis can be traversed by using '/' characters in the path. For example, to put a reference to a Toolbar Button into the Panel which owns the Toolbar:
    var myGrid = new Ext.grid.EditorGridPanel({
        title: 'My EditorGridPanel',
        store: myStore,
        colModel: myColModel,

            text: 'Save',
            handler: saveChanges,
            disabled: true,

        }],
        listeners: {
            afteredit: function() {
    //          The button reference is in the GridPanel
                myGrid.saveButton.enable();
            }
        }
    });
In the code above, if the `ref` had been `'saveButton'` the reference would have been placed into the Toolbar. Each '/' in the `ref` moves up one level from the Component's `ownerCt`. Also see the `added` and `removed` events. | Component

| stateful : Boolean A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startu... A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. The component must have either a `stateId` or `id` assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a component. For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available. To set the state provider for the current page:
    Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
        expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
    }));
A stateful Component attempts to save state when one of the events listed in the `stateEvents` configuration fires. To save state, a stateful Component first serializes its state by calling `getState`. By default, this function does nothing. The developer must provide an implementation which returns an object hash which represents the Component's restorable state. The value yielded by getState is passed to Ext.state.Manager.set which uses the configured Ext.state.Provider to save the object keyed by the Component's `stateId`, or, if that is not specified, its `id`. During construction, a stateful Component attempts to restore its state by calling Ext.state.Manager.get passing the `stateId`, or, if that is not specified, the `id`. The resulting object is passed to `applyState`. The default implementation of `applyState` simply copies properties into the object, but a developer may override this to support more behaviour. You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events. | Component

This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button configs to be added to the toolbar. Note that this is not available as a property after render. To access the top toolbar after render, use getTopToolbar. Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree. | Panel

The title text to be used as innerHTML (html tags are accepted) to display in the panel `header` (defaults to ''). When a `title` is specified the `header` element will automatically be created and displayed unless header is explicitly set to `false`. If you do not want to specify a `title` at config time, but you may want one later, you must either specify a non-empty `title` (a blank space ' ' will do) or `header:true` so that the container element will get created. | Panel

If this panel is a child item of a border layout also see the BorderLayout.Region `floatable` config option. | Panel
| toolTemplate : Ext.Template/Ext.XTemplate A Template used to create tools in the header Element. Defaults to:new Ext.Template('&lt;div class="x-tool x-tool-{id... A Template used to create tools in the header Element. Defaults to:
    new Ext.Template('<div class="x-tool x-tool-{id}">&#160;</div>')
This may may be overridden to provide a custom DOM structure for tools based upon a more complex XTemplate. The template's data is a single tool configuration object (Not the entire Array) as specified in tools. In the following example an <a> tag is used to provide a visual indication when hovering over the tool:
    var win = new Ext.Window({
        tools: [{
            id: 'download',
            href: '/MyPdfDoc.pdf'
        }],
        toolTemplate: new Ext.XTemplate(
            '<tpl if="id==\'download\'">',
                '<a class="x-tool x-tool-pdf" href="{href}"></a>',
            '</tpl>',
            '<tpl if="id!=\'download\'">',
                '<div class="x-tool x-tool-{id}">&#160;</div>',
            '</tpl>'
        ),
        width:500,
        height:300,
        closeAction:'hide'
    });
Note that the CSS class 'x-tool-pdf' should have an associated style rule which provides an appropriate background image, something like:
    a.x-tool-pdf {background-image: url(../shared/extjs/images/pdf.gif)!important;}
| Panel
| tools : Array An array of tool button configs to be added to the header tool area. When rendered, each tool is stored as an Element... An array of tool button configs to be added to the header tool area. When rendered, each tool is stored as an Element referenced by a public property called `tools.<tool-type>` Each tool config may contain the following properties: id : String Required. The type of tool to create. By default, this assigns a CSS class of the form `x-tool-<tool-type>` to the resulting tool Element. Ext provides CSS rules, and an icon sprite containing images for the tool types listed below. The developer may implement custom tools by supplying alternate CSS rules and background images: `toggle` (Created by default when collapsible is `true`) `close` `minimize` `maximize` `restore` `gear` `pin` `unpin` `right` `left` `up` `down` `refresh` `minus` `plus` `help` `search` `save` `print` handler : Function Required. The function to call when clicked. Arguments passed are: event : Ext.EventObject The click event. toolEl : Ext.Element The tool Element. panel : Ext.Panel The host Panel tc : Object The tool configuration object stopEvent : Boolean Defaults to true. Specify as false to allow click event to propagate. scope : Object The scope in which to call the handler. qtip : String/Object A tip string, or a config argument to Ext.QuickTip.register hidden : Boolean True to initially render hidden. on : Object A listener config object specifiying event listeners in the format of an argument to addListener Note that, apart from the toggle tool which is provided when a panel is collapsible, these tools only provide the visual button. Any required functionality must be provided by adding handlers that implement the necessary behavior. Example usage:
    tools:[{
        id:'refresh',
        qtip: 'Refresh form Data',
        // hidden:true,
        handler: function(event, toolEl, panel){
            // refresh logic
        }
    },
    {
        id:'help',
        qtip: 'Get Help',
        handler: function(event, toolEl, panel){
            // whatever
        }
    }]
For the custom id of `'help'` define two relevant css classes with a link to a 15x15 image:
    .x-tool-help {background-image: url(images/help.png);}
    .x-tool-help-over {background-image: url(images/help_over.png);}
    // if using an image sprite:
    .x-tool-help {background-image: url(images/help.png) no-repeat 0 0;}
    .x-tool-help-over {background-position:-15px 0;}

The `xtype` will be looked up at render time up to determine what type of child Component to create. The predefined xtypes are listed here. If you subclass Components to create your own Components, you may register them using Ext.ComponentMgr.registerType in order to be able to take advantage of lazy instantiation and rendering. | Component

## Public Methods

Method | Defined By
--- | ---
| FormPanel( `Object config` ) Parameters: `config` : Object Configuration options Returns: void | FormPanel
- | add( `...Object/Array component` ) : Ext.Component/Array Adds Component(s) to this Container. Description : <ul class="mdetail-params"> Fires the beforeadd event before addin... Adds Component(s) to this Container. Description : Fires the beforeadd event before adding The Container's default config values will be applied accordingly (see `defaults` for details). Fires the add event after the component has been added. Notes : If the Container is already rendered when `add` is called, you may need to call doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can `add` multiple child components if needed while only refreshing the layout once. For example:
      var tb = new Ext.Toolbar();
      tb.render(document.body);  // toolbar is rendered
      tb.add({text:'Button 1'}); // add multiple items (defaultType for Toolbar is 'button')
      tb.add({text:'Button 2'});
      tb.doLayout();             // refresh the layout
Warning: Containers directly managed by the BorderLayout layout manager may not be removed or added. See the Notes for BorderLayout for more details.

This may contain any of the following properties: scope : Object The scope (`this` reference) in which the handler function is executed. If omitted, defaults to the object which fired the event. delay : Number The number of milliseconds to delay the invocation of the handler after the event fires. single : Boolean True to add a handler to handle just the next firing of the event, and then remove itself. buffer : Number Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place. target : Observable Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable. Combining Options Using the options argument, it is possible to combine different types of listeners: A delayed, one-time listener.

Enables events fired by this Observable to bubble up an owner hierarchy by calling `this.getBubbleTarget()` if present. There is no implementation in the Observable base class. This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly. Example:
    Ext.override(Ext.form.Field, {
        //  Add functionality to Field's initComponent to enable the change event to bubble
        initComponent : Ext.form.Field.prototype.initComponent.createSequence(function() {

        }),

        //  We know that we want Field's events to bubble directly to the FormPanel.

        title: 'User Details',
        items: [{
            ...
        }],

Parameters: `index` : Number The index at which the Component will be inserted into the Container's items collection `component` : Ext.Component The child Component to insert. Ext uses lazy rendering, and will only render the inserted Component should it become necessary. A Component config object may be passed in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the inserted Component will not be rendered immediately.

If you are using a Container object to house this Component, then... Render this Component into the passed HTML element. If you are using a Container object to house this Component, then do not use the render method. A Container's child Components are rendered by that Container's layout manager when the Container is first rendered. Certain layout managers allow dynamic addition of child components. Those that do include Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, Ext.layout.TableLayout. If the Container is already rendered when a new child Component is added, you may need to call the Container's doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once. When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind. Omitting the Container's layout config means that a basic layout manager is used which does nothing but render child components sequentially into the Container. No sizing or positioning will be performed in this situation. Parameters: `container` : Element/HTMLElement/String (optional) The element this Component should be rendered into. If it is being created from existing markup, this should be omitted. `position` : String/Number (optional) The element ID or DOM node index within the container before which this component will be inserted (defaults to appending to the end of the container) Returns: void | Component
