Hi,
Please go to Admin -> Theme Options -> Custom CSS => Here put these code and update options
1. Second level menu overlap
nav#main-navigation .menu ul.sub-menu ul.sub-menu{margin-left:0px;}
2. Longer menu names break into two lines
nav.std-menu .menu ul li > a, nav.std-menu .menu ul li > span.title{white-space:normal;}
It will work 100% sure .
Thanks 🙂
With Best Regards
