In addition, it appears that the language that I am using for search
purposes may be incorrect. I've been using the term "popup menu," but
the examples I've found are dropdown menus that allow you to click on a
down arrow in order to display the choices. What I need is to allow
the mouse pointer hovering over a top-level menu item to automatically
cause the sub-menu to display, and then go away if the mouse pointer is
moved elsewhere. Is there a specific term for that sort of thing, or
something that I can type into a search engine that will give me links
to info on that kind of menu?
You can see what I mean by going here (in IE only, because Netscape
doesn't work):

In IE, the menu items in the dark green bar near the top of the page
will display submenus when the mouse rolls over them. Does anyone know
what this sort of thing is called?
