I'm running version 1.3.8 and would like some advice on how to achieve a navigation area like this:
http://www.exo-terra.com/en/index.php

If it's possible, what's the best way to go about it? What addons are best to install as a base etc?

Also is it possible to make the header image change to match the category you are on like that site does?

Any advice/suggestions welcome.
