Hi there!

We're working in the redesign of our web game Striker Manager. ( http://www.strikermanager.com )
We've done several poroosals but none seems to be convincing enough.

The problem is, we have a tree level menu that has to be visible most of the time because user navigate a lot between different sections, so we don't want complex animations, nor dropdown menus. Just a single click to navigate in the current section sibblings.

Can you point us to some examples out there?
