You can add a Relationship attribute to define a relationship between a drop-down property and another property, such that the value of the other property determines the possible values of the drop-down property.

The Relationship attribute is available for the DropDown and DropDownList property value control types.

In a property relationship, a parent property value determines the behavior of a child drop-down property. The child drop-down values are populated based on the value of the parent. If the value of the parent property changes, the child property updates with a list of possible values that are specific to the new parent property.

For more information, see Example of Creating a Relationship Between Two Properties and Adding Them to a Blueprint.
