ProtoShare Forum

I am interested in creating a mega menu that will spawn from a vertical left nav. The default left nav will contain level 1 items. Upon rolling over an L1 item, I would like to display (at right) all L2 and L3 items for that L1.

I am fairly new to Protoshare, but I am pretty sure I need to do something with the vertical state component.

Can someone please provide suggestions for the most efficient way to do this in Protoshare?

Thanks in advance.
