Create a Pop-up Button
A pop-up button is a button control that has an option menu associated with it. Like the independent control button, you must define the pop-up button's option menu, creating all the menu items and writing scripts for them. Unlike a control button, which always looks like any other control button and never has text, a pop-up button may have either text or an image.
