Would like to know how to associate or setup between 2 single select dropdowns. Based on the first dropdown selection, second dropdown should display the related values.
By default this is available in JIRA while creating an issue.
If you select a project , it will display the issue types associated with it in issuetypes drop down.
This association and feature is not given to custom fields dropdowns.
Please do not suggest Cascading dropdown . It has different functionality.
