On the Switch Menu script, how would you make one of the menu options have no sub-menu items AND not produce an empty drop-down field below it? I'm trying to modify it for this site

and I have a few options that don't need drop-down menu's, but I also want the menu to collapse it's current state when one of those non-drop-down items are selected.

ie. If you click on anything above or including HAM & Radio Information, it's the switch menu with drop-down. Anything below that is currently in a table to match the look of the menu, but if you click on one of them (Satellite Images is the only one working at the moment), I would like it to collapse the expanded menu above it.

Thanks.
