What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
This is possible but your inclusion of your products will not come from the Payment gateway but rather from dropdown fields, checkboxes, or radio buttons. You will also need to use a Calculation widget in order to get the value of amount to show up on your total payment amount.
You can check out this guide for more information: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field
Just one note: One downside on this is that the products ordered will not appear on the payment gateway when they make payment. So your source of reference for list of purchased items will be coming from your JotForm email alerts or when you view them on your submissions page here.
Feel free to let us know if you have more questions.
That works. Thank you!
