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 _hs_process_render_hs_selects($hsid, $hierarchy, $size) {
  $form['#tree'] = TRUE;
  $form['#prefix'] = '<div class="selects">';
  $form['#suffix'] = '</div>';
  foreach ($hierarchy->lineage as $depth => $selected_item) {
    $form[$depth] = array(
      '#type' => 'select',
      '#options' => $hierarchy->levels[$depth],
      '#default_value' => $selected_item,
      '#size' => $size,
      // Prevent the select from being wrapped in a div. This simplifies the
      // CSS and JS code.
      '#theme_wrappers' => array(),
      // This alternative to theme_select ets a special class on the level
      // label option, if any, to make level label styles possible.
      '#theme' => 'hierarchical_select_select',
      // Add child information. When a child has no children, its
      // corresponding "option" element will be marked as such.
      '#childinfo' => isset($hierarchy->childinfo[$depth]) ? $hierarchy->childinfo[$depth] : NULL,
      // Drupal 7's Forms API insists on validating "select" form elements,
      // despite the fact that this form element is merely part of a larger
      // whole, with its own #element_validate callback. This disables that
      // validation.
      '#validated' => TRUE,
    );
  }
  return $form;
