Thanks so much! If you could, would you add some documentation for the multiple parameter to examples/reference/widgets/FileInput.ipynb?

Definitely.

Thanks for your contributions @miliante. I'll make the documentation updates in a new PR.

Thank you @philippjfr. Sorry for late replies. I'll keep the documentation in mind for next time.
