Creating navigation with some intelligence

Hi all,
I am attempting to create navigation that has a little bit more intelligence, but really don’t know where to start.

The top level of the navigation as sub nav associated with each. These display on rollover.

What I am unsure of is how to hold the navigation in its on state (with subnav displayed) untl teh user chooses from another section.

I was told that variable and arrays come into play here, but I am still a little green when it comes to these.

Any thoughts on this are much appreciated.
