Convert Yaowsa navigation to dropdown menu nav?

[Keithb]

I'm modifying the Yaowsa theme to fit our site, and like the template layout.  What I was wondering is how would one convert the navigation up top to use the dropdown style as well as the left navigation or parent tree?

Is this possible?

Best I can tell is it's using the {menu number_of_levels="1" template="minimal_menu.tpl"}

Any ideas how to change that to use a dropdown menu that would be built dynamically based on the pages and structure?

I have no idea what it uses for style calls in the menu CSS but you would start by using cssmenu.tpl as menu template then use CSSMenu horizontal style sheet, of course you will have to change some of it to match the theme styles...

If you want it to work in IE6 you will need to add the JS for it...
