Wordpress - Custom taxonomy hide meta box but show in menu
You're looking for the meta_box_cb
argument.
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => false,
'show_admin_column' => false,
'show_in_menu' => true,
'show_in_nav_menus' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'wheel' ),
'meta_box_cb' => false,
);
register_taxonomy( 'wheel', array( 'product' ), $args );
You can also define a custom callback function for displaying your own metabox if you'd like. Refer to the documentation for register_taxonomy().
