Like the check boxes, radio buttons, sliders, and progress bars, another item that can be created with bitmaps and a behavior is the pop-up menu.
Pop-up menus are the little menus that appear in windows and dialog boxes, as opposed to the main menu bar that appears at the top of a screen or window. In the Director authoring environment, you can see examples of these in the Score window and Sprite Inspector. As a matter of fact, just about every window in Director includes some type of pop-up menu.
