Forcing the default mobile menu to be displayed

I know that there are mods people have done to create a side menu rather than the default desktop, but what I'm looking for is a simple solution to force the mobile menu to display at specific resolutions rather than the desktop default menu.

Thanks for the Brad. I will check this out.

Hey Dee Jay - check out the bottom of this old post

We use this for all our apps now - we don't use submenus though so not sure how to handle that.
