Option lists
An option list contains a series of predefined field values. It is useful when you want to provide a short list of values from which the user can select.
To help you better understand the differences between an option list and a taxonomy and when to use one over the other, see best practices.
Note
Option lists were previously known as Data Sources, and the API resource still uses the term /datasources.
Tip
For best practices about migrating option lists, see Importing and exporting data.
