# Class Ext.ux.form.SelectBox

Package: | Ext.ux.form
Defined In: | SelectBox.js
Class: | SelectBox
Extends: | ComboBox
Author: | Corey Gilmore http://extjs.com/forum/showthread.php?t=6392
xtype: | selectbox

Makes a ComboBox more closely mimic an HTML SELECT. Supports clicking and dragging through the list, with item selection occurring when the mouse button is released. When used will automatically set editable to false and call Ext.Element.unselectable on inner elements. Re-enabling editable after calling this will NOT work.

## Config Options

Config Options | Defined By
--- | ---
| allQuery : String The text query to send to the server to return all records for the list with no filtering (defaults to '') | ComboBox
| allowBlank : Boolean Specify `false` to validate that the value's length is > 0 (defaults to `true`) | TextField
| allowDomMove : Boolean Whether the component can move the Dom node when rendering (defaults to true). | Component
| anchor : String Note: this config is only used when this Component is rendered by a Container which has been configured to use an Anc... Note: this config is only used when this Component is rendered by a Container which has been configured to use an AnchorLayout based layout manager, for example: Ext.form.FormPanel specifying `layout: 'anchor' // or 'form', or 'absolute'` See Ext.layout.AnchorLayout.anchor also. | Component
| applyTo : Mixed Specify the id of the element, a DOM element or an existing Element corresponding to a DIV that is already present in... Specify the id of the element, a DOM element or an existing Element corresponding to a DIV that is already present in the document that specifies some structural markup for this component. Description : When `applyTo` is used, constituent parts of the component can also be specified by id or CSS class name within the main element, and the component being created may attempt to create its subcomponents from that markup if applicable. Notes : When 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 component's container. | Component
| autoCreate : String/Object A DomHelper element spec, or true for a default element spec. Used to create the Element which will encapsulate this ... A DomHelper element spec, or `true` for a default element spec. Used to create the Element which will encapsulate this Component. See `autoEl` for details. Defaults to:
    {tag: "input", type: "text", size: "24", autocomplete: "off"}
| ComboBox
| autoEl : Mixed A tag name or DomHelper spec used to create the Element which will encapsulate this Component. You do not normally ne... A tag name or DomHelper spec used to create the Element which will encapsulate this Component. You do not normally need to specify this. For the base classes Ext.Component, Ext.BoxComponent, and Ext.Container, this defaults to `'div'`. 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'
        }
    }
| Component
| autoHeight : Boolean True to use height:'auto', false to use fixed height (or allow it to be managed by its parent Container's layout mana... True to use height:'auto', false to use fixed height (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 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. If the browser is managing the height, 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 height might result in elements needing to be synchronized with the new height. Example:
    var w = new Ext.Window({
        title: 'Window',
        width: 600,
        autoHeight: true,
        items: {
            title: 'Collapse Me',
            height: 400,
            collapsible: true,
            border: false,
            listeners: {
                beforecollapse: function() {
                    w.el.shadow.hide();
                },
                beforeexpand: function() {
                    w.el.shadow.hide();
                },
                collapse: function() {
                    w.syncShadow();
                },
                expand: function() {
                    w.syncShadow();
                }
            }
        }
    }).show();

| 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

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

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'

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',
            fieldLabel: 'Name'
        }]
    });

If `hiddenName` is specified, `hiddenId` can also be provided to give the hidden field a unique id (defaults to the `hiddenName`).

If specified, a hidden form field with this name is dynamically generated to store the field's data value (defaults to the underlying DOM element's name). Required for the combo's value to automatically post during a form submission. See also valueField. Note: the hidden field's id will also default to this name if hiddenId is not specified. The ComboBox id and the `hiddenId` should be different, since no two DOM nodes should share the same id. So, if the ComboBox `name` and `hiddenName` are the same, you should specify a unique `hiddenId`. | ComboBox

Sets the initial value of the hidden field if hiddenName is specified to contain the selected valueField, from the Store. Defaults to the configured `value`. | ComboBox
| hideLabel : Boolean true to completely hide the label element (label and separator). Defaults to false. By default, even if you do not sp... `true` to completely hide the label element (label and separator). 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. Note: see the note for `clearCls`. 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). Note: the default of `'display'` is generally preferred since items are automatically laid out when they are first shown (no sizing is done while hidden). | 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
| hideTrigger : Boolean `true` to hide the trigger element and display only the base text field (defaults to `false`) | TriggerField
| id : String The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to ... 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.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. Note: to avoid complications imposed by a unique `id` also see `itemId` and `ref`. Note: to access the container of an item see `ownerCt`. | Component
| inputType : String The type attribute for input fields -- e.g. radio, text, password, file (defaults to "text"). The types "file" and "p... The type attribute for input fields -- e.g. radio, text, password, file (defaults to "text"). The types "file" and "password" must be used to render those field types currently -- there are no separate Ext components for those. Note that if you use `inputType:'file'`, emptyText is not supported and should be avoided. | Field

An additional CSS class to apply to the div wrapping the form item element of this field. If supplied, `itemCls` at the field level will override the default `itemCls` supplied at the container level. The value specified for `itemCls` will be added to the default class (`'x-form-item'`). Since it is applied to the item wrapper (see Ext.layout.FormLayout.fieldTpl), it allows you to write standard CSS rules that can apply to the field, the label (if specified), or any other element within the markup for the field. Note: see the note for `fieldLabel`. Example use:
    // Apply a style to the field's label:
    <style>
        .required .x-form-item-label {font-weight:bold;color:red;}
    </style>

    new Ext.FormPanel({
    	height: 100,
    	renderTo: Ext.getBody(),
    	items: [{
    		xtype: 'textfield',
    		fieldLabel: 'Name',
    		itemCls: 'required' //this label will be styled
    	},{
    		xtype: 'textfield',
    		fieldLabel: 'Favorite Color'
    	}]
    });
| Component
| itemId : String An itemId can be used as an alternative way to get a reference to a component when no object reference is available. ... An `itemId` can be used as an alternative way to get a reference to a component when no object reference is available. 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`.
    var c = new Ext.Panel({ //
        height: 300,
        renderTo: document.body,
        layout: 'auto',
        items: [
            {
                itemId: 'p1',
                title: 'Panel 1',
                height: 150
            },
            {
                itemId: 'p2',
                title: 'Panel 2',
                height: 150
            }
        ]
    })
    p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
    p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling

The separator to display after the text of each `fieldLabel`. This property may be configured at various levels. The order of precedence is: field / component level container level layout level (defaults to colon `':'`) To display no separator for this field's label specify empty string ''. Note: see the note for `clearCls`. Also see `hideLabel` and Ext.layout.FormLayout.fieldTpl. Example use:
    new Ext.FormPanel({
        height: 100,
        renderTo: Ext.getBody(),
        layoutConfig: {
            labelSeparator: '~'   // layout config has lowest priority (defaults to ':')

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;
        },

        // Component passes itself into plugin's init method
        init: function(c) {
            var p, l = this.listeners;
            for (p in l) {
                if (Ext.isFunction(l[p])) {
                    l[p] = this.createHandler(l[p], c);
                } else {
                    l[p].fn = this.createHandler(l[p].fn, c);
                }
            }

            // 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);

        bottom: (bottom margin),
        left: (left margin)
    }
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:
    {top:0, right:0, bottom:0, left:0}

Maximum input field length allowed by validation (defaults to Number.MAX_VALUE). This behavior is intended to provide instant feedback to the user by improving usability to allow pasting and editing or overtyping and back tracking. To restrict the maximum number of characters that can be entered into the field use `autoCreate` to add any attributes you want to a field, for example:
    var myField = new Ext.form.NumberField({
        id: 'mobile',
        anchor:'90%',
        fieldLabel: 'Mobile',
        maxLength: 16, // for validation

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

This config option is not used when passing a config object into a constructor. This config option is used only when lazy instantiation is being used, and a Plugin is being specified not as a fully instantiated Component, but as a Component config object. The `ptype` will be looked up at render time up to determine what type of Plugin to create. If you create your own Plugins, you may register them using Ext.ComponentMgr.registerPlugin in order to be able to take advantage of lazy instantiation and rendering. | Component

Setting `readOnly=true`, for example, will not disable triggering a ComboBox or DateField; it gives you the option of forcing the user to choose via the trigger without typing in the text box. To hide the trigger use `hideTrigger`. | Field

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,
        tbar: [{
            text: 'Save',
            handler: saveChanges,
            disabled: true,
            ref: '../saveButton'
        }],
        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. | Component

An array of events that, when fired, should trigger this component to save its state (defaults to none). `stateEvents` may be any type of event supported by this component, including browser or custom events (e.g., `['click', 'customerchange']`).

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({
        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

Read-only. This will usually be a <DIV> element created by the class's onRender method, but that may be overridden using the `autoEl` config. Note: this element will not be available until this Component has been rendered. To add listeners for DOM events to this Component (as opposed to listeners for this Component's own Observable events), see the listeners config for a suggestion, or use a render listener directly:
    new Ext.Panel({
        title: 'The Clickable Panel',
        listeners: {
            render: function(p) {
                // Append the Panel to the click handler's argument list.
                p.getEl().on('click', handlePanelClick.createDelegate(null, [p], true));
            },
            single: true  // Remove the listener after first invocation

| 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
