gnirshHere is the situation I have. I have a site with multiple custom post types, which all use the same category structure so different post types can be related to each other dynamically through their category association. For one of the post types I need to list all the categories, but, I need to list only the categories that there are currently posts for. wp_list_categories does this, but because other post types may have entries in categories that this one doesn't, the command lists categories that there is no content for, for this post type.
Does anyone know how I can use wp_list_categories, or another method, to list only the categories that one particular post type has entries for?
