wenn ich mein dropdown-menu habe, und ich will dass wenn sich dieses dropdown-menu öffnet und die kategorien zum auswählen bereitstellt, dass wenn ich auf die Kategorie klicke dann sich ein link öffnet, dies funktioniert mit meinem html code (auf der website version) perfekt, jedoch funktioniert dies nicht in der smartphone ansicht, warum das ?
