如何在symfony2中创建动态表单

I have a formtype, ContactoType, this form contain the next fields:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('nombre','text', array(
                'attr' => array(
                    'placeholder' => 'contacto.nombre'
                )
            ))
            ->add('departamento', 'entity', array(
                'label' => "Departamentos",
                'class' => 'ProductosBundle:Departamento',
                'property' => 'nombre'
            ))
            ->add('fechaEvento', 'birthday',array(
                'input' => 'datetime',
                'widget' => 'single_text',
                'format' => 'dd-MM-yyyy',
                'attr' => array(
                    'placeholder' => 'DD-MM-YYYY',
                    'class' => 'form-control')))
            ->add('promocion','text', array(
                'attr' => array(
                    'placeholder' => 'contacto.promocion'
                )
            ))
            ->add('apodo','text', array(
                'attr' => array(
                    'placeholder' => 'contacto.apodo'
                )
            ))
            ->add('file','file', array(
                'attr' => array(
                    'placeholder' => 'contacto.fichero'
                )
            ))
            ;
    }

The Departamento entity has a field named "requiresadditional" if this is true, and promotion nickname will be displayed, if false they are hidden. Do not know how you could get the field value "requiresadditional"...

As it should do this?Thank!

    You should test your Departamento entity in a FormEvent. Read the documentation about FormEvents here.
