    I have a custom taxonomy register_taxonomy('type', 'blog') where blog is a custom post type.

    When I use wp_dropdown_categories to create a custom filter, why it is empty?

    
    add_action ( 'restrict_manage_posts', 'filters' );
    
    function filters () {
        global $typenow;
    
        if ( 'blog' !== $typenow ) {
            return;
        }
    
        wp_dropdown_categories (
            array (
                'show_option_all' =>  'All',
                'taxonomy'        =>  get_taxonomy ( 'type' )
            )
        );
    }
    

    When I use others like post_tag or category then it works, but it’s empty if use my custom taxonomy.
