Class Ext.menu.BaseItem

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 structural markup for this component. 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. 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.

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).

The CSS class used to provide field clearing (defaults to 'x-form-clear-left').

This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager.

An optional extra CSS class that will be added to this component's container (defaults to ''). This can be useful for adding customized styles to the container or any of its children using standard CSS rules.

How this component should be hidden. 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.

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.

An additional CSS class to apply to the wrapper's form item element of this field (defaults to the container's itemCls value if set, or ''). Since it is applied to the item wrapper, 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.

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:

// 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'
    }]
});

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:

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name',
        labelStyle: 'font-weight:bold;'
    }]
});

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.

The id of the node, a DOM node or an existing Element that will be the container to render this component into. Using this config, a call to render() is not required.

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.

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

The registered xtype to create. 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 child item of a Container is being specified not as a fully instantiated Component, but as a Component config object. 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.
