Hello @
andyo,
Did you have a look at this article:
http://kb.x-cart.com/display/XDD/Step+2+-+applying+design+changes
What you need to do is to define a new view list in the template with your div, e.g.
Code:
<list name="name.of.your.view.list" />
and then assign the Primary menu widget to it as described here:

Please, let me know if it helps.
