I’m having trouble with my footer menu not showing up on mobile. It is under hidden items but when I click show nothing happens.
Based on what you’ve said - I’m guessing this is the Wix Editor.
At the moment, it’s not possible to add more than one menu on the mobile site. We have a feature request open for it here - Request: Creating Multiple Menus for Your Mobile-Friendly Site | Help Center | Wix.com
