Global Field Use Cases

A Global field is a reusable set of fields that you define once and use in any content type across your stack. It helps streamline your content modeling by eliminating the need to recreate the same field configuration multiple times.

You can modify key properties of a Global field at any time based on your requirements. These properties include Select Global Field, Display Name, Unique ID, Instruction Value, Help Text, Multiple, and Non-localizable.
