In your formType :

->add('commerciaux', TextType::class,
            [
                'label'     => 'Apporteur d\'affaire*',
                'attr'      =>
                    [
                        'placeholder'   => 'Apporteur d\'affaire',
                        'list'          => 'bieres'           
                    ]
            ]
        )

In your View :

                    {{ form_row(formulaire.commerciaux) }}
