What Is Magento 2 Add Product To Cart With Custom Options?

Magento 2 custom options should be the primary option for Magento store owners who want to provide customers with additional options on a product’s detail page.

This eliminates the need for online merchants like you to rely on product qualities. Instead, simply add their desired options to the product edit page, specifically under the Customizable Options area. These extra options are usually found beneath the product description. Depending on your business needs, they may be optional or needed.


It’s worth noting that the SKU of these new options can be customized in the backend. Their SKUs, on the other hand, are merely a suffix added to the main product’s SKU. As a result, we won’t be able to track inventories using the SKUs for these extra possibilities. If your inventory is modest and simple, the custom option (customizable options) is ideal. If you have a vast and sophisticated inventory, however, Magento 2 customizable products should be used instead.

Make Group Product and Layered Navigation more complex

Layered Navigation is a Magento 2 catalog navigation feature that allows users to find products faster by filtering the results based on price, category, color, or other product qualities.

A grouped product is a collection of simple products that are related to one another and grouped together to maximize the likelihood of customers purchasing additional items. Each product in a group can be bought independently or as part of a larger group.

The components of a grouped product are listed as individual products in the shopping basket, but they are sold together.

These two features if very important and also complex. 


In these two situations, the most effective way is to use a third-party extension. You can choose what extension you want to customize your product.

Imagine creating a few custom options for a product: a field type and dropdown type. After saving the product getting a javascript error in the console, as shown in the screenshot:

data.forEach is not a function.


Here is an option from Magento 2 forum that you can refer to:

Create file at below location,


var config = {	
    map: {
        '*': {
            "Magento_Ui/js/dynamic-rows/dynamic-rows-grid": 'Custom_Modulename/js/dynamic-rows/dynamic-rows-grid'

Receive payment error with custom options in Magento 2

When consumers use Authorize.net or PayPal to purchase a product with a custom option, they will receive an error message that says, “An error occurred on the server.”, ” Please try placing the order once more.” When you receive such an error, a variety of factors can contribute to the problem. In our case, however, we discovered that the customer had a custom option in the cart that needed to be fixed in Magento core.



You can try the solution we found on Github: 

Go to vendor/magento/module-catalog/Model/Product.php and look for getOptionById method and replace the codes with below:

public function getOptionById($optionId)


  $result = null;

  if (is_array($this->getOptions())) {

      /** @var \Magento\Catalog\Model\Product\Option $option */

      foreach ($this->getOptions() as $option) {

          if ($option->getId() == $optionId) {

              $result = $option;





  return $result;
