How to change the privilege of a field, whose privilege button is not moving (transparent)
User want to make a field from write to read only, but fails to do so. Because, the privilege switch button of a field cannot be moved and is transparent. As shown in the image
The reason behind this behavior of the switch button is, that the field for which user is trying to change the privilege is a mandatory field. If a field is mandatory then its privilege cannot be changed

Once done now, you can change the privilege for that field
Once done, user can go to the module layout and fields and change the make the field mandatory
