Some of my menus have hierarchical submenus, and they aren't working. The little triangle appears but clicking on it doesn't do anything.
Is this supposed to work right out of the box, or do I have to do something to make it work? I am using a bootstrap-based sub-theme.
Thanks.
If you are not using any additional module (just Backdrop), the triangle will not open the submenu. You have to click on the link to show the hierarchy. I assume you are using theme Bartik from the look.
