Add "continue shopping" option to forms before final checkout?

I want to allow customers to shop the site and click "add to order" as many times as they want from various product pages on the website. I'd like their products to populate a single JotForm form where they can check out at the end. How do I accomplish this?

Hi there,

Unfortunately, we do not have such feature. What we had is a simple product system where customers can select multiple products and then  submit the form to proceed with the checkout. However, you can always integrate your form to your website by customizing its form source code and inject custom scripts on your own.

Should you need anything else, let us know.
