Creating Sub Page Menu

Hey, this is a BIG bump? Any help. Cuz I would like to use a sub menu with dynamic highlighting. Man, this must be the WordPress weakness of the century.

This seems to work for me:

Code:

<!-- Main Menu -->
<div id="mainmenu">
	<ul>
	<?php wp_list_pages('sort_column=menu_order&depth=1&title_li='); ?>
	</ul>
</div><!-- / Mainmenu -->

<?php
  if($post->post_parent)
  $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
  else
  $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
  if ($children) { ?>

<!-- Sub Menu -->
<div id="submenu">
  <ul>
  <?php echo $children; ?>
  </ul>
  </div> <!-- / Sub Menu -->

  <?php } ?>

CSS additions:

/* =Current --------------- */
.current_page_item{}
.current_page_item a{
	background: #FFFFFF;
}
.current_page_parent a{
	background: #FFFFFF;}
.current_page_ancestor a{}

You likely have your menu’s li displayed as ‘inline’, if not then you’ll want to add that too.
