Custom menu to scholar? Use the same as u have on

I would like to use another navigation on the scholar theme. Just like the one you have on this site.
I look for a navigation with two column dropdown that is quite fast/alert. The one that follow scholar theme is in my eyes to slow and takes to much space (even though that is a css question i think).

Is it possible to implement the navigation you use in this site?

Thanx in advance.
