To provide a pop-up menu in your application, you have two approaches available. You can either design a menu specifically for use as a pop-up menu, or you can use one of the pull-down menus from the primary menu that you have already designed. If you design a menu specifically for use as a pop-up menu, you will need to skip the top-level, menu bar element by placing a space or some other text in the caption, knowing that it will not be seen. You will see how this works when you build a custom menu specifically for use as a pop-up menu on Day 11, “Creating Multiple Document Interface Applications,” in the section “Adding a Context Menu.”
