Currently toggled sections are only enabled if there are 2 h2's. It has been requested that this could always be turned on. We could potentially turn this into a setting to allow configuration (setting to 0 would always turn it on) See: http://www.mediawiki.org/w/index.php?title=Extension_talk:MobileFrontend&offset=20130903170638&lqt_mustshow=32749#Can_we_force_sections_to_collapse_if_they_don.27t_automagically_do_so.3F_32749
