Increase Categories Menu Dropdown Columns Width

Hi all,

I would like to increase the width of the dropdown columns of the categories menu.

if I just change the css width of the rule

.dropdown-multicolumns .col-x {


to the desired width then the menu doesn't render nicely and even worse some menus

are displayed outside of the grid.

So I guess it is not only the css that should be changed but the template too.

So if someone can help me with the right modifications that should be done in order to get the desired result I would be grateful.
