You mean all the comment block information for a part, accessed by using a field name?

@kevinschmidt– I’m not sure I understand. Have you checked the demos Taxonmony? The entire UI has changed. See attached screenshot.

You can use the lock parameter to stop the meta-box from being dragged.

@jasondalycan– So, you want the second Meal Type field to appear after the ingredient add-more?

You can’t share taxonomies between object types, like CPTs and Users. Use something like this:

function my_register_taxonomy_for_cpts() {
  register_taxonomy_for_object_type('post_tag_user', 'post');
  register_taxonomy_for_object_type('category_user', 'page');
}
add_action('init', 'my_register_taxonomy_for_cpts');

So you want a taxonomy for users?
