Hey guys, the url to the site I'm working on (in drupal using the omega theme) is http://dev.motioncontrol.gotpantheon.com/

I'm trying to implement the off canvas menu for mobile, using a codepen tutorial linked to from this site (http://codepen.io/TimPietrusky/pen/CLIsl)

everything sizes down correctly, but the menu will not show up when the input is clicked. Any help would be greatly appreciated!
