I am using the main menu /admin/structure/menu/manage/main
There are a couple of links that I want to display only in mobile devices, and then also another couple of links that I want to display only in laptop devices. Can I do this without needing two separate menus? I guess one way would be to attach a css class to the relevant links but looking at /admin/structure/menu/item/1/edit there is no option to add classes to a menu link in the menu UI.
I don't want to use CSS nth-child because if in future the menu is edited / reordered then any nth-child rules will get messed up.
So can anyone tell me how to add an option to add classes to individual menu links in the menu UI - and / or some alternative route.
