Following code will display all the subpages of same parent page. also displays the subpages of current page if it is not a subpage.
<?php if($post->post_parent) { $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0$sort_column=menu_order"); $title_heading = get_the_title($post->post_parent); } else { $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0"); $title_heading = get_the_title($post->ID); } if ($children) { ?> <h2> <? echo $title_heading ?> </h2> <ul> <?php echo $children; ?> </ul> <?php } ?>
