How to create a feedback form with a multiple property of the “file” type in Bitrix?

Question

1C-Bitrix

There was a need to create a feedback form in which the client could attach several files. So that when filling in the field, another one would appear and so on, until the client attaches everything that is needed.
Has anyone solved a similar problem and can suggest a direction?

Answer 1

I did not take a steam bath for a long time and created 10 answers for this field. Immediately I display all ten answers in html (1 is shown, the rest are in hidden divs) - on clicking "add more" I just show the next hidden div) - often 10 files are enough.
