This feature is available in Power Actions starting with v4.1.0 and above.
Many of our clients requested Power Actions for Jira to provide the possibility to have a screen succession in addition to a single screen in the Jira issue. These screens would involve complex interactions where a certain field depends on one, two or more fields, eventually looking into a database or LDAP, and so on.
We implemented a wizard enabling you to design and establish an entire flow inside a single button. You can now create cascading fields inline on the page, going through the steps that you define.
