这是result:

以及code:

add_action( \'add_meta_boxes\', \'wpse_42440_add_custom_box\' );
add_action( \'admin_head\', \'wpse_42440_script_direct_print\' );

function wpse_42440_add_custom_box()

    add_meta_box(
        \'wpse_42440_sectionid\',
        __( \'Blogroll\' ), 
        \'wpse_42440_blogroll_box\',
        \'page\'
    );
    add_meta_box(
        \'wpse_42440_sectionid\',
        __( \'Blogroll\' ), 
        \'wpse_42440_blogroll_box\',
        \'post\'
