| * require_once('DB_NestedSet/NestedSet/Output.php'); |

| * // get data (important to fetch it as an array, using the true flag) |
| * $data = $NeSe->getAllNodes(true); |
| * // change the events for one of the elements |
| * $data[35]['events'] = array('onexpand' => 'alert("we expanded!");'); |
| * // add links to each item |
| * foreach ($data as $a_data) { |
| * $a_data['link'] = 'http://foo.com/foo.php?' . $a_data['id']; |
| * } |
| * $params = array( |
| * 'structure' => $data, |

| * 'icon' => $icon, |
| * 'expandedIcon' => $expandedIcon, |

| * 'textField' => 'name', |
| * 'linkField' => 'link', |
| * ); |
| * $menu =& DB_NestedSet_Output::factory('TreeMenu', $params); |
| * $menu->printListbox(); |
