Demo Site Layout - Navigation Panel

Demo Site Layout - Navigation Panel

The demo site for jQuery Mobile 1.4.0 has the exact layout I'd like to use for my app - that is:

 - For desktop width, navigation panel is persistent
 - For mobile width, navigation panel is hidden, accessible from icon

Anyone know of a straight-forward layout that does this?  I'm trying to open and persist the panel in a css media query but with no luck.
