This tree menu

[dhimok]

Hello, Can someone help me with this recursive function. As the function is right now it shows all parents and children. What I want to do is to expend parent to show children and when i click on a child then the menu does not collapse but remains. any ideas? thanks in advance

 

function menu($parent = 0, $level = 0)
{
   // where parent of 0 means it's top-level
   $retval = "";

   $sql = mysql_query("SELECT * FROM " . TABLE_CATEGORIES . " WHERE parent='$parent'  ORDER BY sort ASC");

	$retval .= "<div id=\"verticalMenu\">\n";
	$retval .= "<ul>\n";

   while ($row = dbFetchAssoc($sql))
  	{
    	extract($row);
        $retval .= "<li><a href=\"".friendlyURL($category_id)."\">" .$category."</a></li>\n";

	$retval .= menu($category_id, intval($level) + 1);
   }
   		$retval .= "</ul>\n";
	$retval .= "</div>\n";

   return $retval;
}
