How to Edit Category Tree?

[easypie]

What's going on is I have a dozen link and sub links under {% block sidebar-categories %} that I want to style using CSS. I want to give a unique background image to the first and last tag in category_tree. For example, if forloop.first then first ul tag will get menu_top.png and menu_bottom.png for forloop.last. But how do I figure out how to do that?

I skimmed through satchmo_category.py and other files but still confused. Something like this: http://i48.tinypic.com/v8g5ty.png

I meant the first li tag and last li tag.

This is really more a django template / basic css question, but what you can do is test for forloop.first and last, and in those cases change your <li> to include a class="first" or class="last"

Then style the <li> first and last appropriately in css.
