Menu.removemenuitem() - MACROMEDIA FLASH 8-COMPONENTS LANGUAGE Reference

You first drag a Menu component to the library and then add the following code to Frame 1:
/**
Requires:
- Menu component in library
*/
import mx.controls.Menu;
// Create an XML object to act as a factory.
var my_xml:XML = new XML();
// The item created next does not appear in the menu.
// The createMenu() method call (below) expects to
// receive a root element whose children will become
// the items. This is just a simple way to create that
// root element and give it a convenient name.
var menuDP_obj:Object = my_xml.addMenuItem("XXXXX");
// Add the menu items.
menuDP_obj.addMenuItem({label:"1st Item"});
menuDP_obj.addMenuItem({label:"2nd Item"});
// Create the Menu object.
var my_menu:Menu = Menu.createMenu(this, menuDP_obj);
// Show and position the menus.
my_menu.show(100, 20);
var interval_id:Number = setInterval(remove, 2000, my_menu);
function remove(the_menu:Menu):Void {
// Delete all menu items.
the_menu.removeAll();
clearInterval(interval_id);
the_menu.show(100, 20);
}
