Easily only use side (mobile) nav menu?

[GlifTek]

Hi,
I'm using the Massively theme for a page of mine.
I have too many menu items to use the "top bar" menu for desktop @media dimensions, so I'm trying to use only the mobile slide out menu version on all platforms.

I've removed the @media sections in the #nav and #/.navToggle areas in main.css, and kept their contents.
Mobile menu works fine, yet going over 986px in screen width, the nav links do not appear.

Any quick and easy workaround for this?
Thanks!
