in the original theme setting, the menu sub items are showed when click on the little arrow beside the main item, however I would like to change this setting and make it show automatically and directly. Can I add some CSS to change this? Or other things I can do?
Example in my site: https://yu-xuan-li.com
under "Photo Project" there are "project1, 2, 3.....". How should I make them show without clicking?
