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_flat_select($hierarchy, $dropbox, $config) {
  $selection = array();
  if ($config['dropbox']['status']) {
    foreach ($dropbox->lineages_selections as $lineage_selection) {
      $selection = array_merge($selection, $lineage_selection);
    }
  }
  else {
    $selection = $hierarchy->lineage;
  }
  $options = array();
  foreach ($selection as $value) {
    $is_valid = module_invoke($config['module'], 'hierarchical_select_valid_item', $value, $config['params']);
    if ($is_valid) {
      $options[$value] = $value;
    }
  }
  $element = array(
    '#type' => 'select',
    '#multiple' => $config['save_lineage'] || $config['dropbox']['status'],
    '#options' => $options,
    '#value' => array_keys($options),
    // Use a #theme callback to prevent the select from being wrapped in a
    // div. This simplifies the CSS and JS code.
    '#theme' => 'hierarchical_select_select',
    '#attributes' => array(
      'class' => 'flat-select',
    ),
  );
  return $element;
