@zoonini Thanks for the answer!
It’s weird that it is like that by default, since I rarely ever see a website with collapsed submenus, it just looks messy.
I’ve fixed this pretty simple in the end.
- Enabled “open on click” on navigation in editor.
- Made java script file and registered it in functions.php (I am using my own copy of TT3 theme)
- Made simple JQuery that toggles all submenu’s on click.
It can be done even better most likely, but it will work for now since I am in the rush!
