recursive function with collapsible menu

Hey Guys.

Ma' brain is stuck.
I'm currently working on customizing a menu. Got the following code, but wan't the list
to be collapsible without using any Javascript/Jquery, only pure PHP.
Do you guys have any idea how to do that?

PHP Code:


			
function display_children($parent, $level) {

    $result = mysql_query("SELECT a.id, a.label, a.link, Deriv1.Count FROM `menu` a  LEFT OUTER JOIN (SELECT parent, COUNT(*) AS Count FROM `menu` GROUP BY parent) Deriv1 ON a.id = Deriv1.parent WHERE a.parent=" . $parent);

    echo "<ul>";

    while ($row = mysql_fetch_assoc($result)) {

        if ($row['Count'] > 0) {

            echo "<li><a href='" . $row['link'] . "'>" . $row['label'] . "</a>";

            display_children($row['id'], $level + 1);

            echo "</li>";

        } elseif ($row['Count']==0) {

            echo "<li><a href='" . $row['link'] . "'>" . $row['label'] . "</a></li>";

        } else;

    }

    echo "</ul>";

}



display_children(0, 1);

All help will be appreciated!
