A container used to display menus. It should be placed inside a Menu.

Supported event: onOpen .

Note: to have better performance, onOpen is sent only if non-deferrable event listener is registered (see Deferrable ).

To load the content dynamically, you can listen to the onOpen event, and then create menuitem when OpenEvent.isOpen() is true.

Default HtmlBasedComponent.getSclass() : menupopup .
