After i tried several Iterations (Foreach utilizing First and Iteration) within the system's Mainmenu template i had to realize that it would need quite some tweaking at the php files in order to get the above questioned feature done.

I meanwhile fixed our quite complex Structure in disabling the system Mainmenu and using multible Pico's instead and also utilizing the > MIGHTY < Menublock's aswell as an Single Multimenu as an central Navigation Element on top.

Pico, in my eyes, is one of the most powerful/essential Moduls for Xoops. Keep up the fantastic and all through professional Work.
