M is for Menus

The Flex Menu control creates pop-up menus of individually selectable choices, that can have cascading sub-menus. (Similar to the application menus (e.g. File, Edit) or right-click menus in most application.)

A Menu is created with a call to the Menu class static createMenu() function. Of course you'll have to pass some data representing the menu items and structure to the createMenu() call.

   // create the menu data structure
  var menuData:Array = [ "Item 1", "Item 2", "Item 3" ];
 
  // create the menu
  var menu:Menu = Menu.createMenu( parent, menuData, false );
 
  // show the menu
  menu.show()
