如何在symfony 3中将集合添加到集合形式

Question

我在symfony 3中有3种表单类型

PanneauType，它是所有下一个集合的父项

            ->add('faces', CollectionType::class, array(
                'entry_type' => FacePanneauType::class,
                'entry_options' => array('label' => false),
                'allow_add' => true,
                'allow_delete' => true,
            ))

FaceType

->add('agendas', CollectionType::class, array(
                'entry_type' => AgendaType::class,
                'entry_options' => array('label' => false),
                'allow_add' => true,
                'allow_delete' => true,
                'attr' =>['class'=>'agendas']
            ))

AgendaType

->add('debut', null, ['attr'=>['class'=>'form-control']])
 ->add('fin', null, ['attr'=>['class'=>'form-control']])

为此，您将需要一些Javascript：）
