The Product Customizer component can be used on the Product Details Page (PDP) to display attachments and/or a subscription form.

An attachment is the optional and cost-free customization of a product.

Example of a PDP with the Product Customizer component displaying product attachments.

Product subscriptions facilitate recurring sales by automatically scheduling the purchase of a specific product at the frequency requested by the customer.

Example of a PDP with the Product Customizer component displaying the product subscription.

• If you plan to use the Product Customizer component to display attachments, make sure to set up Assembly Options.
• If you plan to use the Product Customizer component to display a subscription form, make sure to set up Subscriptions. The Product Customizer integration with the Subscription module is native and will be automatically enabled when subscription settings are detected.

1. Add the product-customizer app to your theme dependencies in the manifest.json. For example:

2. Add the product-assembly-options block as a child of the store.product template (PDP template). This is enough to enable the subscription form.

3. Declare the product-assembly-options props for your scenario.

1. To display attachments of a product on the Product Detail Page (PDP), declare the product-assembly-options block and add the assembly-option-input-values block as its child.

2. Use the blocks exported by the product-customizer app to create a solution that best suits your specific scenario.

Block name	Description
assembly-option-item-image	Displays the attachment image.
assembly-option-item-quantity-selector	Displays a quantity selector.
assembly-option-item-name	Displays the attachment name.
assembly-option-item-price	Displays the attachment price.
assembly-option-item-customize	Displays the Customize button. When clicked, it opens a modal that allows customers to customize the attachment.
assembly-option-item-children-description	Displays a summary with all selected attachments.

3. Declare the props for the chosen blocks according to your scenario. For example:

While building your solution, note that you can receive inputs from three types of attachments:

• Predefined options: Predefined attachment options set in the Permitted Values field. Set up the optionsDisplay prop from the assembly-option-input-values block to define how these options are displayed.
• Free text: Text input. Depending on the value set in the Maximum Number of Characters field in the attachment settings, shoppers may or may not have a character limit for this attachment.
• Boolean: Boolean attachment options set in the Permitted Values field. Customers can select the attachment by clicking the checkbox.

Check the following example where the three attachment types are implemented:

Check out below how the product attachment displayed above was added to the Catalog:

When an attachment is set as required, all attachment options are automatically made available to consumers. On the other hand, if an attachment is not required, the Add customization button is rendered, as shown in the example above. This gives shoppers the option to add or not an attachment to their product.

Also, keep in mind that the Checkout does not natively display the customized product option selected by the customer. To display the product in the Checkout with the selected attachments, it is necessary to customize the Checkout page, allowing it to read and render product information.
