Subcategories in columns rather than rows

I am working on a website and need to change the subcategories to look like this http://mibelloboutique.com/index.php?main_page=index&cPath=56 (my site). I need the subcategories in 3 columns like mine and have changed the categories to list per row as 3. This is the version of zen cart being used Zen Cart 1.3.8a. This is the site I need to change and the page that needs to change. Scroll down past the picture....

There are no subcategory pics uploaded. On my site, I didn't have to do anything special, no mods, etc....

Thoughts?

Add to your stylesheet```
.categoryListBoxContents {float: left;}

The default stylesheet has a rule that includes this, which has been changed so that some other element would not float left. The right way to do that is to separate out the element you actually want to change and give it its own rule instead of changing the property for a whole list of elements. Perhaps this was the one:```
.centerBoxContents, .specialsListBoxContents, .categoryListBoxContents, .centerBoxContentsAlsoPurch {
	text-align:center;
	}
