Hi,
I have quite the same problem:
In the option “CSS of Menu To Hide” (Advanced settings), how to hide the CSS of more than an element?
The website (www.igorkishcka.com) has 3 languages. I had hidden only the Portuguese (Brazil) menu (hiding #menu-menu-1. The other native menus (#menu-menu-2 and #menu-menu-3 -> English and Spanish) are still appearing.
Thank you.
