Menu Control in Flex4:
The Menu contol is a pop-up control. It containes a submenu. You can select a indivisual item from menu control. You use only Actionscript for create a pop-up Menu control. There is no MXMl tag. You can set the coordinate x, y in show() method as an arguments. The syntax of create a pop-up Menu control is following.

You can display menu contol using show() method and pass the coordinate as an arguments.
