I used the Hero template for my headers - one for Front page, and one for all other pages (without the second bar with the hero image). I created a navigation dropdown set to only be visible on smaller devices, but when activated, the menu doesn’t show. When I inspect the element with Google Chrome Developer tool, it’s there, but wholly invisible. The site is in maintenance mode, but am happy to provide credentials for you to look at it. I have a menu assigned to both headers, but nothing. Same for both headers.
I am stumped.
