Getting started
What is Modern DFFS
What it does, who it is for, and how it fits modern SharePoint and Microsoft 365.
Install & deploy
Upload the package to an app catalog — tenant-wide, or scoped to a single site collection — then add it to the sites that need enhanced forms.
Turning DFFS off
Hand a form back to SharePoint, deactivate across many lists at once, and clean up afterwards. No list data is ever lost.
Build your first form
Five minutes from an empty list to a working form with its own layout and a rule that fills a field in by itself.
Licensing & editions
What each edition includes, how licensing works, and what happens when a trial ends.
