Basically, you want the equivalent of DHTML popup menus.

To implement them, you cannot use the navigation tags.  They will only
give you information about the currently expanded nodes.  You need to
use the Model API instead.  (Note that should you desire to do it, you
can use the navigation tags to get to the current page level and then
combine it with the Model API to get all children of the current page
whether expanded or not.)  Search the InfoCenter for information about
the Model API.
