showmenu2 to show first two levels on default

[Vlob]

I need to configure a showmenu2 the following way

I have a menu in 4 levels

starting with 3 items on level 1, each having 3 sublevels, those 12 items should be always visioble and from there on curr+1


whatever i try, the other second levels won't stay visible...

any suggetions?
