Magento 2 : Allow customer to edit custom options on Cart

Question

I am trying to add functionality to allow a customer to edit options.

I have created a Module Vendor/COptions. This is loading custom options and select, however is not getting user selected options.

I would like to know how to received selected options and check if the option is selected. At the moment this line in Select.php is not receiving anything, and the variable $checked is null.

$configValue = $this->getProduct()->getPreconfiguredValues()->getData('options/' . $_option->getId());

in Vendor/COptions\view\frontend\templates\cart\item\default.phtml :

 <?php $selectedOptions = $block->getSelectedOptionList(); ?>
 <?php //$_options = Mage::helper('core')->decorateArray($block>getOptions())
    $_options =  $block->getOptions() ?>  
  <?php if ($_options AND count($_options)):?>
    <dl>
   <?php foreach($_options as $_option): ?>
  <?php echo $this->getOptionHtml($_option) ?>
   <?php endforeach; ?>
   </dl>
  <?php endif; ?>

in Vendor\COptions\Helper\Rewrite\Product:

public function getCustomOptions(\Magento\Catalog\Model\Product\Configuration\Item\ItemInterface $item, $simple="")
{

    $product = $item->getProduct();
    $coptions = [];
    $coptions = $product->getOptions();
    $options = array();

   if ($coptions) { 
   foreach ($coptions as $option) {
   $itemOption = $item->getOptionByCode('option_' . $option->getId());

           /** @var $group \Magento\Catalog\Model\Product\Option\Type\DefaultType */
                  $group = $option->groupFactory($option->getType())
                      ->setOption($option)
                      ->setConfigurationItem($item)
                      ->setConfigurationItemOption($itemOption);



                  if ('file' == $option->getType()) {
                      $downloadParams = $item->getFileDownloadParams();
                      if ($downloadParams) {
                          $url = $downloadParams->getUrl();
                          if ($url) {
                              $group->setCustomOptionDownloadUrl($url);
                          }

                              $group->setCustomOptionUrlParams($urlParams);
