Simple Category Tree

[some name not taken]

Hmmm... all_subcats_products is not doing anything for me. - I'm still stuck with the three basic categories that won't expand to show the products, ie: a fully expanded tree.

I figure that this should work:

<?php
$content = '';
$content .= $_SESSION['category_tree']->build_category_string('ul', 'li', '', 0, 2), $categories_id = 0, retrieve_categories_tree_array(), build_deepest_level_children(), 

retrieve_deepest_cats_array($categories_1, $categories_2, $categories_3);
?>
