Piklist works well with existing Post Types… those created with the standard WordPress function register_post_type. However, you can add some extra power to your Post Types by registering them the Piklist way. Piklist extends the register_post_type function with extra parameters to enable extra features. You can use the standard register_post_type() parameters, plus the additional Piklist Custom Post Type parameters.
To learn more about registering Post Types with Piklist, please read about the piklist_post_types filter.
