remove_meta_box( 'mf_1', 'page', 'normal' );
}
this way you can just add the ids in the array and as many as you want

What you want is get_post_meta or get_post_custom. Those will return arrays which you will have to loop over and format yourself. the_meta uses get_post_custom. You can use its code as a ...
