[已解决] Spliting Languages inside the Language swithcer in multiple column.

I want to split the Language Switcher into 2 or three columns.
I tried this code from the forum, but it did´t work.
I´m using the Avada Theme.

Thanks for helping me out.

.drop_down .narrow.wpml-ls-item .second .inner ul {
width: 300px !important;
}

.drop_down .narrow.wpml-ls-item .second .inner ul li {
width: 150px;
float: left;
}
