i would like add for this form input new from the module additional and change the sfWidgetFormDoctrineChoice for multiple checkbox. how can i make it?

THX!

sfWidgetFormDoctrineChoice has an option called 'expanded' that if it's on true then will display the options with checkboxes (check this example from the symfony's Jobeet).

In your UserForm.class.php you have to put something like this (check your BaseUserForm.class.php)

<!-- lib/form/doctrine/UserForm.class.php -->
...
public function configure(){

    $this->setWidget('groups_list', new sfWidgetFormDoctrineChoice(array(
              'multiple' => true, 
              'model' => 'Group', //check that on your base
              'expanded' => true, //set checkboxs
    )));

}
...
