Dear Jalila,
Unfortunately, it is not possible to create dynamic fields (like you have described) within DocuWare Forms. Currently, we don't have any information about the future planning.
At the moment, I cannot give you a proper Workaround for this Situation. The only thing you could do, is using Merge Forms and Workflows to append information based on user input after submission.
We would like to invite you to provide your feedback on our customer feedback forum: http://docuware.uservoice.com/
There you can share new ideas and feedback regarding all DocuWare modules and get in contact with our product team. Our partners and customers can vote for these ideas and thus specify whether the functions are useful.
The higher a feature is voted, the better are chances that it will be implemented in future versions.
With best regards,
Pascal Tham
