Problem styling pages and their subpages separately

I’m having a template problem involving listing pages in the sidebar with sub-page, I’ve built off of the solution referenced here:

I have a problem with Fold Page List’s implementation. I’d like to style the “page_folder” ancestor separately from the child “page_items”, however I cannot. The ancestor and children are both wrapped in an LI tag that doesn’t terminate until after the child items, making anything done to the parent inherited by the children.

The resultant html:

<li class="page_item current_page_item page_folder">Ancestor
<ul>
<li class="page_item">Child One</li>
<li class="page_item">Child Two</li>
<li class="page_item">Child Three</li>
</ul>
</li>


And the php:

<?php
// get id of current page
$g_page_id = $wp_query->get_queried_object_id();
// find ancestor pages
$ancestors = _wswwpx_page_get_ancestor_ids($g_page_id);
// find topmost ancestor
$ancestor = reset($ancestors);
// build args
$args = "child_of=".$ancestor ."&sort_column=menu_order&title_li=";
wswwpx_fold_page_list ($args, 2); ?>


Ideal html:

<li class="page_item current_page_item page_folder">Ancestor</li>
<ul>
<li class="page_item">Child One</li>
<li class="page_item">Child Two</li>
<li class="page_item">Child Three</li>
</ul>

Note how the UL is outside of the first LI. This is important to me so I can have ancestors use a separate style from the children, with a unique background image, ems size, and dynamic highlighting when that ancestor’s page is selected.

Am I doing something wrong? Is there a way for me to work around this or is this a bug to be fixed in the way WP outputs the children?
