$field->prototype() not using custom template in Collection

[iainheng]

I have a collection field

 $this->add('option_types', 'collection', [
    'type' => 'form',
    'template' => 'products.partials.option_types_field',
    'options' => [
       'class' => ProductOptionTypesForm::class,
         'label' => false,
    ]
]);

class ProductOptionTypesForm extends Form
{
    public function buildForm()
    {
        $this
            ->add('option_type', 'select', [
                'label' => false,
            ])
            ->add('option_value', 'text', [
                'attr' => [
                    'class' => 'option-value'
                ]
            ]);

    }
}

And my custom template to generate a table of the option fields

<?php if ($showField): ?>
    <?php foreach ((array)$options['children'] as $child): ?>
        <tr class="option-row">
            <td>
                <div class="form-group">
                    <?php echo $child->getChild('option_type')->render([], false, true, false) ?>
                </div>
            </td>
            <td>
                <div class="form-group">
                    <?php echo $child->getChild('option_value')->render([], false, true, false) ?>
                </div>
            </td>
            <td>
                <ul class="segmented">
                    <li class="first-child">
                        <a href="#" class="btn remove-option" title="remove"><i class="fa fa-trash-o"></i></a>
                    </li>
                </ul>
            </td>
        </tr>
    <?php endforeach; ?>
<?php endif; ?>

The form generate correctly using my custom template when I call {!! form_widget($form->option_types) !!} but it always generate using default collection template when I call form_widget($form->option_types->prototype())

Is this a bug or anything that I am doing wrongly?

@iainheng if i understood correctly, you need to pass custom template to the options array, same where you put 'label' => false.
