Implementation of the Hierarchical Select API that allows one to use a hardcoded hierarchy. When it becomes to slow, you should move the hierarchy into the database and write a proper implementation.

Code

function _hs_smallhierarchy_transform_recurse($parent, &$hs_hierarchy, $relative_hierarchy, $separator = '|') {
  foreach ($relative_hierarchy as $item => $children) {
    $generated_item = $parent . $separator . $item;
    $hs_hierarchy[$parent]['children'][] = $generated_item;
    $hs_hierarchy[$generated_item]['label'] = $children['label'];

    // Build the subsequent levels.
    if (isset($children['children'])) {
      _hs_smallhierarchy_transform_recurse($generated_item, $hs_hierarchy, $children['children'], $separator);
    }
  }
}
