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.

Each plugin can then call methods or respond to events on the component as needed to provide its functionality.

A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup.
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: 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. |

render( [Element/HTMLElement/String container ], [String/Number position ] ) : void Render this Components into the passed HTML element.
If you are using a Container object to house this Component, the...
Render this Components 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 nothnig but render child components sequentially into the Container. No sizing or positioning will be performed in this situation.
