Have dropdown menu in top navigation display in two columns

try something like:

li#menu-item-913:hover ul { width: 300px; }
li#menu-item-913:hover ul li { width: 45%; float:left; }

Thanks so much Alchymyth!

I’m very much a beginner when it comes to css, so sorry for this question, but where exactly should I place that in my css file?

Thanks a lot for your help!

it might possibly be the best if you install a custom css plugin https://www.ads-software.com/extend/plugins/search.php?q=custom+css to add any changes; use for example the custom css section of the ‘jetpack’ plugin https://www.ads-software.com/extend/plugins/jetpack/

this way, the formatting changes will be preserved when you update your theme.

or alternatively add the changes at the very end of style.css of your theme

Wow! You are the best Alchymyth!!

That worked like a charm. Thanks so much for taking the time to help me out!!!

Have a wonderful day,
Dan
