mod on CSS Horizontal Dropdown

[gjh42]

You can address the menus on the right with increasing amounts of negative left positioning, like this:

#dropMenu>ul>li+li+li+li+li+li>ul {
   left: -4em !important;
   }
#dropMenu>ul>li+li+li+li+li+li+li>ul {
   left: -12em !important;
   }
#dropMenu>ul>li+li+li+li+li+li+li+li>ul {
   left: -20em !important;
   }
#dropMenu>ul>li+li+li+li+li+li+li+li+li>ul {
   left: -1.9em !important;
   }

The last ones need a small offset because they have only one column of items.
