Okay, I thought you just need to add the css to the parent link. I added the css-class “sub-menu-columns” now the every sub-menu link, but it’s still not working
And that’s what I put in the css
.sub-menu {
width: 410px;
}
.sub-menu-columns ul.sub-menu li {
display: inline-block;
float: left;
width: 200px;
}
.sub-menu-columns ul.sub-menu li:nth-child(odd) {
float: left;
margin-right: 10px;
}
.sub-menu-columns ul.sub-menu li:nth-child(even) {
float: right;
}
