Menu items spread over 2 rows

Hi there I am trying to come up with a better solution than the one I have at the moment.
I have a number of menu items that I would like to split up over two rows. Mu current solution is to have 2 menus with works and gets me the solution from a design perspective. However from a mobile perspective when viewed on a mobile device it renders both menus and its not as neat as I would want it.
Is there a way to create a single menu with two rows.

Hi
you could use the merge feature from Mobile Menu CK (only in Pro version)
www.joomlack.fr/en/joomla-extensions/mobile-menu-ck

this allows you to have your 2 menus into a single mobile menu. Is that what you need ?

I will have a look at that, thanks
