如果我完全理解这个问题，那么您可以在注册CPT时设置对页面属性的支持，如下所示：

add_action( \'init\', \'register_products_post_type\' );
function register_products_post_type() {
    $labels = array(
        \'name\' => \'Products\'
    );

    $args = array(
        \'labels\'        => $labels,
        \'public\'        => true,
        \'rewrite\'       => array(
            \'with_front\'    => false
        ),
        \'has_archive\'   => true,
        \'hierarchical\'  => true,
        \'menu_position\' => 5,
        \'supports\'      => array( ..., \'page-attributes\', ... )
    );

    register_post_type( \'products\', $args );
}
