Can we set multiple levels of hierarchy of different issue types?

[Mahima Srivastav]

I want to create multiple levels of hierarchy for my custom issue types.

• Program
  
  • Sub-Program
    • Feature
      • Variant
        
        • Part Type
          • Design-1
          • Design-2
          • Design-3

Is this possible?

Hi Mahima,

You can do something similar using Advanced Roadmaps - but that is only available for Premium Subscriptions. 

For regular, out-of-the-box Jira, your hierarchy is not possible. All you can do is:

Epic > Story > Sub-task
