The mission was to display sub-pages of the current page you are on in the left nav and once you hit the bottom of the hierarchy to show pages which are parallel to that page within the same branch of the hierarchy.
After some digging and experimentation I came up with the following which executes perfectly in only a few lines of code.
<?php
$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0&depth=1");
if ($children == "")
$children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0&depth=1");
?>
<ul>
<?php echo $children; ?>
</ul>
<?php endif; ?>Of course you style to taste…
That’s it! Used in conjunction with a standard WordPress top-navigation and breadcrumbs you can easily display page sensitive multi-level navigation for your super-complex multi-level site!
