JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
I am not sure if I understood your concern correctly. Could you please provide us an example?
What do you mean by print a list of docs? Are the docs in your form as a file upload? Or is it an embedded PDF form?
If you wish to embed a PDF document on your form, then that is possible using this widget: https://widgets.jotform.com/widget/pdf_embedder
If you want to display the widget or other fields based on your user's input, then that should be possible using conditional logic: https://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic
Using conditions, you can show/hide fields depending on the rules you setup, you can make calculations, insert values on a text box, etc...
I hope that helps.
