submenu link display

Hi, I would like to add something like this ‘v’ to the right of the main menu link when there’s a submenu for that main menu link. Right now, the only way you can tell if there’s a submenu is by hovering over it.

Never mind, I figured this out.

.menu li > a:after { content: ‘ ▾’; }
.menu li > a:only-child:after { content: ”; }
