Unfortunately that’s not the problem I have – Bootstrap is only loaded once on my site.
I’m working on comparing the ‘More’ menu with the mobile menu. The mobile menu works correctly, so I’m trying to work out what the differences are. So far I can see that the Javascript which fires when a sub-menu in the more menu is clicked changes the ‘aria-expanded’ property on the sub-menu from “false” to “true” and adds the class “open”. However, the menu disappears at the same time and the properties are reset next time you click ‘More’ to show the emnu again.
I wonder if it will be OK if I can get it to stay on-screen rather than disappearing after an item is clicked?
