You can create submenus to organize and group similar menu items together.
A submenu is a menu item that displays a new menu with additional menu items when clicked. The menu item created to display a submenu shows a triangle on its right side.
The following table describes the non-alphanumeric characters that can be used to control the display and behavior of the caption for a submenu. Non-alphanumeric characters not listed are reserved for future use as special menu characters.
