Creating a Hamburger Button for Drop-Down Menu for Mobile

I am interested in adding a "Hamburger" button for a drop-down menu on the mobile side of our site, like the one Xara has on the Service Center mobile site at http://www.xara.com/us/servicecenter/ . I may have missed it, but there doesn't seem to be a button or a widget for that. Of course, I am still learning Xara 11 (and would add I am very much enjoying it). Does anyone have anything to suggest on this?

Welcome to TG.
Press F1 (help) and search with "Single button NavBars".
There are posted examples; this is one: http://www.talkgraphics.com/showthre...le-devices-use.
