I'm using AIT Business Finder theme located here: http://www.ait-themes.com/wordpress-themes/business-finder-directory-listing-wordpress-theme/
I need to display 100 categories and would like them to display like Yelp.com has their categories. I've searched for a plugin to accomplish this and I've come up empty handed. Can anyone suggest a way to display categories like Yelp's? Thanks!
