Configuring a dependent enumeration value set

You can configure a value set customization so that the values of one enumeration type attribute are set based on the value of another enumeration type attribute.

About this task

This task uses the Dependent Enumerations value set provider to populate the list of values for one attribute based on the value of another attribute. Both attributes are of the enumeration type. In this example, the set of values for the Browser attribute are set based on the value of the OS attribute.
