I am trying to create a tree menu for a medium sized website.
I'm having troubles finding a template that does what I need.
Can this even be done in dreamweaver? I've tried playing around with the navigation bar tool but cant get to make sub menus appear.
I was wondering if anyone knew of a template that:

Will keep only one sub menu folded out (ie. Automatically retracts the currently opened sub menu when a new one is chosen)
Uses rollover images
Highlights the current page (optional, but desirable)


11111 11111
22222 >1111
>2222 >1111
>2222 22222
>2222 33333
33333 44444

An example close to what I want is here: (the menu on the left)

Thanks for your time,
