The formatters for Data Sections are defined in a specialised project called “PRINT”. This project is usually configured to be visible only for administrators but since it is a regular project you can also allow other users access to it if needed.
Note: Even though R/W users can access the PRINT project edits and changes to PRINT items can only be made by the Admin. If a R/W user changes something, the changes will not be synced to the server and will not be usable in the project.
This part of the documentation walks you through setting up your own formatters. To use them see the corresponding section in the user guide that explains adding them to your documents and selecting data to show.
