Multicolumn menu problem

Hello again ...
I have a problem with the submenu. I've put 2 or more columns and doesn't work.
Only one column appears and also the white background does not cover everything.
Why? What's wrong?
I need help please.
Thanks.

Please add this code to override.css and make sure override is enabled in template settings.

Code: Select all

.childcontent .gkcol {
    margin: 0 -1px;
}


Sorry
not working
Why?

Hi

Works when I look at Your site Maybe You need to clear joomla or browser cache to see the difference.
