The short version. Permissions are set per field, not just per form. One form can show different things to different roles.
The three settings
Required
The form can’t be submitted without it. Use it sparingly — every required field is one more reason somebody leaves the form as a draft.
Visible To
Which roles can see the field at all. Invisible fields aren’t greyed out; they aren’t there.
Edited By
Which roles can change it. A field can be visible to everyone and editable by the PM only.
The case this exists for
A T&M-style form with a labor table: the foreman fills in names, trades and hours. The billing rate column is visible and editable to the PM and the office, and invisible to the foreman. One form, one submission, one record — and nobody in the field is looking at rates.Next
