The Menu control is quite similar to the Popup Menu control, only closer to the actual structure of a menu bar. Each Menu control remains visible on the screen at all times and looks like a command button.

When the mouse pointer is moved over the Menu control, the control's caption takes a three-dimensional look. In addition, an arrow pointing down suggests that the menu leads to a submenu. It is possible to have menus without submenus, which behave similarly to command buttons, but they have the same look as the other Menu controls.
