Drop-Down Menu Bar Project

I guess what I need to know is can 2 drop-down be added within the menu.js? Can this menu.js script be edited to add a drop-down on the end? I am NOT looking for a completely different Menu Bar.

This is how the menu bar is NOW. This menu bar has NO drop-down links. Can this menu script be modified?

PLEASE READ this HERE and understand it completely.

I am not a programmer, this is just a hobby I like.
Thanks, Mike
