I have a site that is using a child theme based on Twenty Twelve. I have two menus on the site. When the menus get toggled to a mobile version's button, the main menu button works fine and expands as expected. The secondary menu turns to a button but doesn't seem to toggle properly. When clicked, it... um, "flickers" a bit but does not expand. I inspected the source code and see that it has a 'toggle' style added to it. Not sure why it won't actually toggle. I have looked in the forums but got lost in most posts being about menus not working at all. I also tried removing plugins (to no avail) before the site was made live.
The address for the site is: http://www.cantonballet.com/. Any and all help is appreciated. Hopefully the main Diva will be able to diagnose this in no time.
Thank you much!
