We have two questions about form2content pro:
1. have options to not showing on publications on (front-end) not filed fields (the blank fields).
2. Fields to be visible for different type user groups (public, registered, etc... ).
1) I don't understand this sentence... what is the question?
2) We do not have ACL (permissions) per field in a form. You can make certain fields only visible in the back-end (maybe that was question one?).
Please read the F2C documentation before asking questions! Thank you if you've done so
