Not only did this fix the space but I can actually see Homepage submenus now! For years I was wondering why I could never see the submenus so I had to literally manually start adding them into every page. After your fix I saw duplicate Page submenus so at first I was confused. After deleting the ones I put in manually I also noticed that the ones that re-appeared actually were able to slide.    Please add the CSS fix code mentioned in post into the original UNA code. It is needed for Homepage Submenus and other page submenus to work correctly. @Andrey Yasko @Alex T⚜️ @Anton L @LeonidS
