Hello,
Thanks for your response Don Lee.
I tried, but it doesn't work.
When i choose GK Extra menu in template manager it works nicely.
but when i choose GK Dropline menu in template manager, i see no change at the third level when i configure the colums of the second level of my menu item.
It seems the GKMenu.php have columns options but not the GKDropline.php but maybe i missed something and i will try again.
regards
