Hi Laola,


To make a field read-only, you can set “disabled: true”.

For the second question, please see the Checkout demo here – https://www.htmlelements.com/demos/form/checkout/

You will see that the field at orderSummary.order.products is dependent on the information contained in the payment method fields.

You can do this by updating the value inside the onValueChanges callback
