Symfony - Override field options (required = false to required = true)

I want to accomplish the following:

FormType -> If my checkbox is checked, hide a normally required field and make it required = false, so I can submit my Form.

So I need to override a specific form field if my checkbox is checked. Example...

Form:

$builder->add(
    'checkbox',
    CheckboxType::class,
    [
        'label' => 'checkbox',
        'required' => false,
        'mapped' => false,
        'attr' => [
            'class' => 'checkbox',
        ]
    ]
);

index:

$('.checkbox').change(function () {
    if ($('.checkbox').is(':checked')) {
        $(".end-date").hide();
    } else {
        $(".end-date").show();
    }
});

how do i continue?

i tried something like this (somehow it's not working):

$builder->addEventListener(FormEvents::PRE_SUBMIT, function (FormEvent $event) {
            $form = $event->getForm();
            $config = $form->get('what_ever_field')->getConfig();
            $options = $config->getOptions();

            $form->add(
                'what_ever_field',
                get_class($config->getType()->getInnerType()),
                array_replace(
                    $options,
                    [
                        'required' => false,
                    ]
                )
            );
        });

But it makes no sense because the checkbox and the listener have no relation.

I think it would be much easier to dynamically change the field's required attribute via JS after it's rendered on the page. You're half way there:

JS

$('.checkbox').change(function() {
    if ($('.checkbox').is(':checked')) {
        $(".end-date").removeAttr("required");
        $(".end-date").hide();
    } else {
        $(".end-date").attr("required","required");
        $(".end-date").show();
    }
});

This JQuery code can be optimized, but that's about it. Hope it helped.
