I have two pages intended to appear as sub items that will drop down under a parent heading. I designated them as sub items under their parent in Pages and in Menus in the dashboard.In Menus, they display correctly as sub items until I save. At that point, they revert to parent level. My in-progress site is (here). I have deactivated plugins to see if that was the problem, but it didn't help. Other threads suggested this could be a CSS issue. Any and all suggestions are appreciated.
