You can do it with sfWidgetFormChoice this way:
in form class:



$this->widgetSchema['template_id' = new sfWidgetFormChoice(array('choices' =>TemplateCategory::getChoices()));

in TemplateCategory class:



class TemplateCategory extends BaseTemplateCategory

{

  public static function getChoices()

  {

    $result = array();

    $treeObject = Doctrine::getTable('TemplateCategory')->getTree();

    $rootColumnName = $treeObject->getAttribute('rootColumnName');



    foreach ($treeObject->fetchRoots() as $root) {

      $options = array(

          'root_id' => $root->$rootColumnName

      );  

      foreach($treeObject->fetchTree($options) as $node) {

        $result['-' . $node->id] =  str_repeat('-', $node->level) . ' ' . $node->name;

        foreach ($node->templates as $tpl) {

          $result[$tpl->id] = str_repeat('-', $node->level + 1) . ' ' .  $tpl->name;

        }

      }   

    }   

    return $result;

  }

}
