Im trying to change my new post categories check boxes to only show the deepest level of children(no parent cats). I see this function on line 339 of /wp-admin/includes/meta-boxes.php
<?php wp_terms_checklist($post->ID, array( 'taxonomy' => $taxonomy, 'popular_cats' => $popular_ids ) ) ?>
but there's no depth $arg or anything like it according to the codex.
Anyone have any ideas? Thx!
