What I'm trying to do is make the wp_list_cats function indicate which categories have "parents" by making a list with bullets and sub-bullets.
Example: http://www.thenonist.com (click on the categories button in the left hand sidebar)
In other words, I want my category list to look like this.
- Parent category 1
- Sub-category (under PC 1)
- Parent category 2
I have templates installed in which this hierarchy occurs, but I don't see any special parameters in the code that would order such a thing to happen.
