Symfony form CollectionType remove empty value

I'm using Symfony 3.3 and I have a form with a CollectionType like : 

$builder->add('links', CollectionType::class, array(
    'label' => false,
    'entry_type' => LinkType::class,
    'entry_options' => ['data_class' => CompanyLink::class],
    'allow_add' => true,
    'allow_delete' => true,
    'prototype' => true,
    'by_reference' => false,
));

I followed the documentation : https://symfony.com/doc/current/reference/forms/types/collection.html

This is what I have in my view :

enter image description here

So, the form displays well data already in my database (one line each time) but it always adds an empty field in addition.

How can I remove this empty field? Because I want to have this line only I click on the button "Ajouter".

Thanks!

I think in your function of rendering form you have setData(),

to render the form without data, you just need to do this sample:

//Your main entity
$mainEntity = new Entity();
//adding the other entity into collection variable of other entity of main entity
$mainEntity->addOtherEntity(new otherEntity());

$form = $this->createForm(
        MainEntityForm::class,
        $mainEntity
);

hope it helps.

This post is a bit old ihope it's not to late. I found a solution, even if you travel the collectionType field with a twig for. To avoid having this empty field after your for loop, add

{% do form.your_field.setRendered %}

It worked for me, hope it will do the same for you :)
