sure.

that was just a hint, not the exact solution ;)
try something like this: (attention, untested)
function display_children($parent, $level) {
// retrieve all children of $parent
$result_btnt = mysql_query('SELECT nt FROM btnt '.
'WHERE bt="'.$parent.'";');
$output=array();
// display each child
while ($row = mysql_fetch_array($result_btnt)) {
// indent and display the title of this child
// call this function again to display this
// child's children
$output['children'][]=display_children($row['nt'], $level+1);
}
return $output;
}
I just wonder how you get the root node.
