we're running jQuery MatchHeight inside your Tabs widget. For the first tab, everything works fine. The other tabs don't work, because MatchHeight doesn't know they're present until shown. What we'd need is a trigger for when tabs are changed to run MatchHeight again. I guess there already are triggers in your main.min.js, but i can't read this file. Could you tell me which triggers are available or provide an unminifed version of main.js?
