You create a custom properties definition that determines how the custom property appears in vRealize Automation. You can add the custom property to a blueprint so that you can verify that the property displays the check box, drop-down menu, or other control type as expected.

To create and test the custom property definitions, you need a blueprint that is already entitled to you or to a test user account to which you have access. This test blueprint allows you to create the custom property, add it to a blueprint, and then verify that the custom property has the expected appearance. After you validate the custom property, you can add it to your production blueprints as needed.
