How can I make dependencies of form fields upon widget User Permissions

I've a widget with address field and wish to add few User Permissions upon which my widget will show/hide address field

I checked your form and I noticed that you have created your own widget called GPS Location Finder. I think you can just add the User permission that shows/hides the address field as a setting on your Widget. The setting can be "Show Address" just like the other settings on your widget.

If this is not suitable for your case, please provide us more information on what are you trying to achieve so we can further check this.
