Thank you
If I'm doing it right.. this fixes the mobile sub menu perfectly, but breaks the main menu by adding "About Us" after every sub menu entry. I've left the edit live so that you can see.
/*Info*/
.header-nav-item:nth-of-type(2) a:after, .header-menu-nav-item:nth-of-type(2) a:after{
content:"\a About Us";
white-space: pre !important;
}
edit..
It actually breaks other 2nd level mobile menu titles too
