Make parent categories not selectable

I really doubt this is filterable, so jQuery comes to rescue 🙂 The Code add_action( ‘admin_footer-post.php’, ‘wpse_22836_remove_top_categories_checkbox’ ); add_action( ‘admin_footer-post-new.php’, ‘wpse_22836_remove_top_categories_checkbox’ ); function wpse_22836_remove_top_categories_checkbox() { global $post_type; if ( ‘post’ != $post_type ) return; ?> <script type=”text/javascript”> jQuery(“#categorychecklist>li>label input”).each(function(){ jQuery(this).remove(); }); </script> <?php } The Result Advanced There’s a caveat: whenever selecting a sub-category, it … Read more

How to hide a specific category posts in my monthly archive?

And if you want a dropdown … Read more
