When the hidden checkbox option for a field is enabled that field will be hidden from view within the Fulcrum mobile apps, as well as the web app, when records are being created or edited. It is helpful when you wish to include data with your records but do not need the field users to access or see this data.
The "Hidden" option is available for all field types except Label fields.
Fields set to hidden will be printed on default PDF reports.
Calculation fields that are set to be hidden will still run their calculations when the record is opened in the record editor.
