dwebservices Having reviewed now after toggling the option in T3 framework to turn on responsive mobile menu and clearing cache, The toggle menu appears now in responsive mobile mode
the responsive menu does not work properly. it is unusable on smartphone. there is a bug
As apparently seen, This is site specific bug as the responsive menu works fine in demo site in default stage. You may try the following measures to see if it helps :
1) Try disable 3rd party extensions one by one to see for JS conflict
2) Try to replace this file from default Joomla package i.e./media/jui/js/jquery-migrate.min.js ensuring to take backup of the current file
