A menu tree would have to be implemented in javascript. You can use php to output the HTML and javascript, but you need the javascript first.

Search Google for "menu tree HTML javascript" or try something like this:

what exactly do you want to know? a categorie my be more left than a subcategorie, as shown at the win explorer.

The best way is to use a database with a table simular to

cat_name, this_uid, parent_uid

then you can put entries into it such as

food, 1, 0
fruit, 2, 1
apple, 3, 2
apple, 4, 2
bread, 5, 1
cars, 6, 0
ford, 7, 6
escort, 8, 7
fiat, 9, 6

then you can pull back all the entries with a zero parent id these are the top level then search for all the entires with a parent id that matches the 'this_id' for each entry.

something like

<PRE>

<BODY>
<?

require_once("/usr/local/apache/includes/mysql_database.inc");

show_sub(0, 0);

function show_sub($parent_id, $indent)
{
$this_struct=new mysql_dbase("struct");
$this_struct->connect();

$query="select * from struct where parent_uid like '".$parent_id."'";
$retval=$this_struct->do_query($query, "y");
if ( $retval > 0 )
{
    while ( $fields=$this_struct->get_data() )
    {
        for ( $loop=0; $loop<$indent; $loop++ )
        {
            echo "&nbsp;&nbsp;&nbsp;&nbsp;";
        }
        echo $fields['cat_name']."<BR>";
        show_sub($fields['this_uid'], ($indent+1));
    }
}

}

?>
</BODY>

This uses one of my own classes to handle the
database stuff but you should be able to get
the idea. The display is a little basic
but again you should be able to make up your
own layout.
