@webquadro: Thank you for the submenu function. I had some trouble with the list. Code was not valid. Fixed it like this:

Code:

//****************************************************//
//** FUNCTION: get_subpages()                       **//
//**                                                **//
//** Function to display subpages.                  **//
//****************************************************//
function get_subpages($parent) {
    $data = menu_data();    
    $parent = $parent . "/";
    $output = array();

    foreach( $data as $menu) {
        if ($menu['parent_slug'] == $parent){
            $output[] = "<li><a href='" . $menu['url'] . "' title='" . $menu['title'] . "'>"
                                                    . $menu['title'] . $menu['parent'] . "</a></li>";
        }
    }
    
    $menu_string = implode("\n", $output);
    if ($menu_string != "") {
    echo "<ul>".$menu_string."</ul>"; }
    }
