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_process_render_db_visible($hsid, $dropbox) {
  $element['#tree'] = TRUE;
  $element['#theme'] = 'hierarchical_select_dropbox_table';

  // This information is necessary for the #theme callback.
  $element['title'] = array(
    '#type' => 'value',
    '#value' => t($dropbox->title),
  );
  $element['separator'] = array(
    '#type' => 'value',
    '#value' => '›',
  );
  $element['is_empty'] = array(
    '#type' => 'value',
    '#value' => empty($dropbox->lineages),
  );
  if (!empty($dropbox->lineages)) {
    foreach ($dropbox->lineages as $x => $lineage) {

      // Store position information for the lineage. This will be used in the
      // #theme callback.
      $element['lineages'][$x] = array(
        '#zebra' => ($x + 1) % 2 == 0 ? 'even' : 'odd',
        '#first' => $x == 0 ? 'first' : '',
        '#last' => $x == count($dropbox->lineages) - 1 ? 'last' : '',
      );

      // Create a 'markup' element for each item in the lineage.
      foreach ($lineage as $depth => $item) {

        // The item is selected when save_lineage is enabled (i.e. each item
        // will be selected), or when the item is the last item in the current
        // lineage.
        $is_selected = $dropbox->save_lineage || $depth == count($lineage) - 1;
        $element['lineages'][$x][$depth] = array(
          '#value' => $item['label'],
          '#prefix' => '<span class="dropbox-item' . ($is_selected ? ' dropbox-selected-item' : '') . '">',
          '#suffix' => '</span>',
        );
      }

      // Finally, create a "Remove" checkbox for the lineage.
      $element['lineages'][$x]['remove'] = array(
