Data template fields
Current version: 10.2
Data template fields define the user interface controls and other properties that influence how the field behaves in the Content Editor and Page Editor. They are primarily used to control the structure of a field and can provide automatic error checking when you enter data in the field. The template field is equivalent to a property in object-oriented programming, or a column in a relational database.
Note
Every field in a template must exist within a section, which organizes fields into logical and reusable groups.
