Thank you all for your comments and help.
After much search and frustration and reading further on on JQuery and what it can do, I have found what I was looking for.

I found at justjquery
under plugins a plugin called ssubnav1.1. which you can download Here and view a demo of what it can do Here

I was able to install and make it work on a new site I am creating, the solution looks elegant and functional.

I am using derwood 10 theme as a trial . you can see what my progress on the site is at Aquijuarez.

If all goes as planned I will be creating a theme with JQuery functionality on the menu.

I will of course include a tutorial on how to modify the menu and implement it.

Thanks Mamba, will give it a go.
