This module defines the "hierarchical_select" form element, which is a greatly enhanced way for letting the user select items in a hierarchy.

Code

function _hierarchical_select_get_form_item($form, $name) {
  if (isset($form['#name']) && $form['#name'] == $name) {
    return $form;
  }

  // The current form item apparently is not the one we're looking for, so try
  // to find it in the child form items.
  foreach (element_children($form) as $child) {
    $form_item = _hierarchical_select_get_form_item($form[$child], $name);
    if ($form_item !== FALSE) {
      return $form_item;
    }
  }

  // No match in the children either, so return FALSE.
  return FALSE;
}
