Angreas09 Sub Menu

[BarryH]

Andreas09 has its main menu along the top, then form each of those, a sun menu appears on the left hand side. A further submenu should appear below each of those submenus, but at a smaller size and off set to the right.
When I do this, the final submenu opens below but at the same size and directly below.  If I use firefox addon to look at the code, and add the word "sub" it look as I want it. Code examples are
What happens
<a class="nav" target="_top" href="http://mail.edgecumbecollege.school.nz/wb/pages/curriculum/social-sciences/geography.php">Geography</a>  and change it to
<a class="nav sub" target="_top" href="http://mail.edgecumbecollege.school.nz/wb/pages/curriculum/social-sciences/geography.php">Geography</a> it works.

How do I get this  work in the code  (If you use the address in the code you can see what I am trying to say)
