Displaying subcategories list as a multicolumn list

I am trying to show my subcategories as a columed list when you hover over the main category. The funcionality will be essentially the same as www.monoprice.com

I have followed this walkthough http://kb.cs-cart.co…-multicolumns#3 but I dont see any change.

I am using a Dropdown Vertical list.

anyone know a addon which can help get this type of mification to basic theme of cs-cart 4.1.2 ???
