How to add Placeholder on choice list with MDbootstrap and symfony

Question

Based on this documentation of MDB: https://mdbootstrap.com/docs/jquery/forms/select/

I have created this form

 public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('categorie', EntityType::class, [
            // This field shows all the categories
            'class'    => Categorie::class,
            'Placeholder' => 'Select choice',
            'mapped' => false,
            'multiple' => true,
            'attr' => ['class' => 'mdb-select']
            ])

Like what i have coded i want to see 'Select choice' in place holder But this the result in picture :

My probleme is i see directly the resulat of class Categorie, but at first i need to see the placeholder!

Any solutions please?

PS: My question is not duplicate to this : How to add placeholder on input in Symfony 4 form?

because i'm use MaterialDesignBootstrap and not bootstrap, i have used placeholder like the response of that question and not work.

Sorry same problem, maybe it's a bug in Mdbootstrap – Khalil Apr 21 '19 at 15:55
Did you use ? // Material Select Initialization $(document).ready(function() { $('.mdb-select').materialSelect(); }); – Heyden7611 Apr 21 '19 at 16:19
Screen your twig please – Heyden7611 Apr 22 '19 at 07:27
{{ form_row(form.categorie) }} – Khalil Apr 22 '19 at 07:36

Ok and if you do

$builder
    ->add('categorie', EntityType::class, [
    // This field shows all the categories
    'label' => 'test for categories',
    'class'    => Categorie::class,
    'placeholder' => 'Select choice',
    'mapped' => false,
    'multiple' => true,
    'required' => false,
    'attr' => [
        'class' => 'mdb-select',
     ],
    'label_attr' => [
        'class' => 'mdb-main-label',
     ]
    ]);
