Each Panel has built-in support for expanding and collapsing.
*Note: Only Ext.Panels and all subclasses of Ext.Panel may be used in an accordion layout Container.
*This class is intended to be extended or created via the {@link Ext.Container#layout layout} * configuration property. See {@link Ext.Container#layout} for additional details.
*Example usage:
