Can custom fields be added without a meta box?
Add this code in functions.php add_action(‘admin_init’, ‘wpse_87339_admin_init’); function wpse_87339_admin_init() { wp_enqueue_script(‘wpse_87339_admin’, get_stylesheet_directory_uri() . ‘/js/admin.js’, array(‘jquery’)); } and create new js file name admin.js and then add the below code in it jQuery(document).ready(function($) { // Remove all .postbox classes from sidebar $(‘#side-sortables .postbox’).removeClass(‘postbox’); // Remove .postbox from specific metabox (page attributes) $(‘#pageparentdiv’).removeClass(‘postbox’); });
