# Menu Bar Overview

A menu bar encapsulates a set of commands in menu form. A menu bar appears as a bar at the top of a panel and contains a set of menu titles. A sample menu bar appears in the following figure:

Menu Bar and Pull-Down Menu

A menu title ending in an exclamation point is called an immediate action menu and does not have an associated pull-down menu. When the user clicks an immediate action menu, a command executes immediately.

A menu title without an exclamation point has a pull-down menu. The menu can contain menu items and submenu titles. When you select a submenu title, submenu items appear on the side. A sample submenu appears in the following figure:
