Answer 1

As far as I understand, you want to have an HTML template where you will fill in data based on user input as well as data coming from your database. This is possible in iText in general, however you would need to do a lot of work, especially if you want to have a template for the PDFs that you are going to generate (as well as the template for the HTML form for capturing data).

It would be nice to have a tool where we design the HTML form and the form with which the output PDF is going to be generated interactively and maybe even using the same resources, sub-forms, sub-templates etc. Then the only thing the technical person would do is to bind the actual data to the form elements. The template will have the logic to show/hid elements or any other conditions that you might come up with. It would simplify the workflow a lot.

iText is working on a product called Dito which was announced in GIDS 2018 in Bangalore, India and a demo session was given. Dito is going to do exactly what you want and what I describe above. You can find the presentation here: http://www.developermarch.com/developersummit/downloadPDF/Dito.pdf
