submenu question

try this code to add a border to the column : line 346 in the file
develop.ocmorgenstond.nl/modules/mod_max.../css/maximenuhck.php

line 346 isn't working. But checking with Firebug I discovered that the element we need to ajust is the ul.maximenuck2, starting on line 198 of the same file.
This is what I did:
Line 200
Line 204
Now I have a vertical line between the columns

I have another question:

I want to use 5 columns, but I can't get the last column filled with submenu items. Altho I did set the next submenu item to create a new column. Can you tell me why that is?

set the columns width in percent, like "20%" instead of 180px
you don't have sufficient space to put 5 x 180px

ok, I have tried to find this setting in the Module mod_maximenuck, but can't find it. Should I tweak this setting in PHP file?

how did you create your colums ??
