## Config Options

Config Options | Defined By
--- | ---
| allowDomMove : Boolean Whether the component can move the Dom node when rendering (defaults to true). | Component

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

A tag name or DomHelper spec used to create the Element which will encapsulate this Component. You only need to specify this when creating or subclassing the base classes Ext.Component, Ext.BoxComponent, and Ext.Container. The more complex Ext classes use a more complex DOM structure created by their own onRender methods. This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:
    {
        xtype: 'box',
        autoEl: {
            tag: 'img',
            src: 'http://www.example.com/example.jpg'
        }
    }, {
        xtype: 'box',
        autoEl: {
            tag: 'blockquote',
            html: 'autoEl is cool!'
        }
    }, {
        xtype: 'container',
        autoEl: 'ul',
        cls: 'ux-unordered-list',
        items: {
            xtype: 'box',
            autoEl: 'li',
            html: 'First list item'
        }
    }

True to use height:'auto', false to use fixed height (defaults to false). Note: Although many components inherit this config option, not all will function as expected with a height of 'auto'. Setting autoHeight:true means that the browser will manage height based on the element's contents, and that Ext will not manage it at all. | BoxComponent
| 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

True to use width:'auto', false to use fixed width (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. | BoxComponent

A DomHelper configuration object specifying the element structure of this Panel's body Element. This may be used to force the body Element to use a different form of markup than is created automatically. An example of this might be to create a child Panel containing 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: 'New Message',
        collapsible: true,
        renderTo: Ext.getBody(),
        width: 400,
        bodyCfg: {
            tag: 'center',
            cls: 'x-panel-body'
        },
        items: [{
            border: false,
            header: false,
            bodyCfg: {tag: 'h2', html: 'Message'}
        }, {
            xtype: 'textarea',
            style: {
                width: '95%',
                marginBottom: '10px'
            }
        },
            new Ext.Button({
                text: 'Send',
                minWidth: '100',
                style: {
                    marginBottom: '10px'

The id of an existing HTML node to use as the panel's body content (defaults to ''). The specified Element is appended to the Panel's body Element by the Panel's afterRender method after any configured HTML has been inserted, and so the document will not contain this HTML at the time the render event is fired. | Panel

A config object that will be applied to all components added to this container either via the items config or via the add or insert methods. The defaults config can contain any number of name/value property pairs to be added to each item, and should be valid for the types of items being added to the container. 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'}. | Container

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 eg:
    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();

The label text to display next to this Component (defaults to '') This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use:
    new Ext.FormPanel({
        height: 100,
        renderTo: Ext.getBody(),
        items: [{
            xtype: 'textfield',

        }]
    });

True to completely hide the label element (defaults to false). By default, even if you do not specify a fieldLabel the space will still be reserved so that the field will line up with other fields that do have labels. Setting this to true will cause the field to not reserve that space. This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use:
    new Ext.FormPanel({
        height: 100,
        renderTo: Ext.getBody(),
        items: [{
            xtype: 'textfield'
            hideLabel: true
        }]
    });
| Component

Supported values are "visibility" (css visibility), "offsets" (negative offset position) and "display" (css display) - defaults to "display". For Containers which may be hidden and shown as part of a card layout Container such as a TabPanel, it is recommended that hideMode is configured as "offsets". This ensures that hidden Components still have height and width so that layout managers can perform measurements when calculating layouts. | Component
| hideParent : Boolean True to hide and show the component's container when hide/show is called on the component, false to hide and show the... True to hide and show the component's container when hide/show is called on the component, false to hide and show the component itself (defaults to false). For example, this can be used as a shortcut for a hide button on a window by setting hide:true on the button when adding it to its parent container. | Component

An HTML fragment, or a DomHelper specification to use as the panel's body content (defaults to ''). The HTML content is added by the Panel's afterRender method, and so the document will not contain this HTML at the time the render event is fired. This content is inserted into the body before any configured contentEl is appended. | Panel

The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to access the component later and you do not have an object reference available (e.g., using Ext.ComponentMgr.getCmp). 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. | Component

A single item, or an array of child Components to be added to this container. Each item can be any type of object based on Ext.Component. Component config objects may also be specified in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the added Component will not be rendered immediately. To take advantage of this "lazy instantiation", set the Ext.Component.xtype config property to the registered type of the Component wanted. For a list of all available xtypes, see Ext.Component. If a single item is being passed, it should be passed directly as an object reference (e.g., items: {...}). Multiple items should be passed as an array of objects (e.g., items: [{...}, {...}]). | Container

The standard separator to display after the text of each form label (defaults to the value of Ext.layout.FormLayout.labelSeparator, which is a colon ':' by default). To display no separator for this field's label specify empty string ''. This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use:
    new Ext.FormPanel({
        height: 100,
        renderTo: Ext.getBody(),
        items: [{
            xtype: 'textfield',
            fieldLabel: 'Name',
            labelSeparator: '...'
        }]
    });

A CSS style specification to apply directly to this field's label (defaults to the container's labelStyle value if set, or '').``. This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use:

True to mask the panel when it is disabled, false to not mask it (defaults to true). Either way, the panel will always tell its contained elements to disable themselves when it is disabled, but masking the panel can provide an additional visual cue that the panel is disabled. | Panel

An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. (defaults to ''). This can be useful for adding customized "active" or "hover" styles to the component or any of its children using standard CSS rules. | Component
| pageX : Number The page level x coordinate for this component if contained within a positioning container. | BoxComponent
| pageY : Number The page level y coordinate for this component if contained within a positioning container. | BoxComponent

An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality. | Component

The id of the element, a DOM element or an existing Element that this component will be rendered into. When using this config, a call to render() is not required. If this Component needs to be managed by a Container's layout manager, do not use this option. It is the responsiblity of the Container's layout manager to perform rendering. See render. | Component

An array of events that, when fired, should trigger this component to save its state (defaults to none). These can be any types of events supported by this component, including browser or custom events (e.g., ['click', 'customerchange']). See stateful for an explanation of saving and restoring Component state. | Component

The unique id for this component to use for state management purposes (defaults to the component id if one was set, otherwise null if the component is using a generated id). See stateful for an explanation of saving and restoring Component state. | 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());
Components attempt to save state when one of the events listed in the stateEvents configuration fires. You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events | Component

The title text 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 don't 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

| FieldSet( `Object config` ) Parameters: `config` : Object Configuration options Returns: `` | FieldSet

Adds a Component to this Container. Fires the beforeadd event before adding, then fires the add event after the component has been added. You will never call the render method of a child Component when using a Container. Child Components are rendered by this Container's layout manager when this 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 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. 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 specify a layout manager which creates and manages the type of layout you have in mind. Omitting the layout config means that a basic layout manager is used which does nothnig but render child components sequentially into the Container. No sizing or positioning will be performed in this situation. Parameters: `component` : Ext.Component/Object The Component to add. Ext uses lazy rendering, and will only render the added Component should it become necessary, that is: when the Container is layed out either on first render or in response to a doLayout call. A Component config object may be passed instead of an instantiated Component object. The type of Component created from a config object is determined by the xtype config property. If no xtype is configured, the Container's defaultType is used. For a list of all available xtypes, see Ext.Component. Returns: `Ext.Component` component The Component (or config object) that was added with the Container's default config values applied. example:
       var myNewGrid = new Ext.grid.GridPanel({ store: myStore, colModel: myColModel }); myTabPanel.add(myNewGrid); myTabPanel.setActiveTab(myNewGrid);

| render( [`Element/HTMLElement/String container`], [`String/Number position`] ) : void Render this Component into the passed HTML element. 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
