THANKS SO MUCH for the clear explanation!  Now I've achieved what I 
wanted.  I've seen a lot examples showing how to create menus either 
table based or list based.  But I wanted something mixed as shown below:

Resourses
   Labtops
      > one
      > two
      > three
Vendors
   IBM
   APPLE
   DELL

First and second level menu always show.  First level just static titles 
(not clickable).  Only clicking the second level menu can the third 
level show up.  So I make table cell of the second level menu to be a list.

It works but I sure open to any better ways to do this.
