How do I make deposits an option?

I am using the product list and I have also looked at the videos on how to make them with the calculation widget with the single choice but I am having trouble trying to get it to work for the list. Is this at all doable?

Are you looking to allow your respondents to make an initial payment/deposit first and just complete the remaining balance later? We would like to apologize for any inconvenience. I'm afraid that the feature you are looking for is not available with the payment field that you can set up on your form.

We can forward your concern to our developers as a feature request. But before we do, kindly confirm that I have understood your concern correctly. If, in any case, I have misunderstood your concern, please do not hesitate to let us know and please give us more details about your concern.
