Adding and Creating Custom Ticket Fields, and Ticket Statuses

[eric_hitchcock]

I'm new to JSM and working on creating custom categories for level 1 and level 2 (sub categories) that only technicians and admins to JSM can see. 

I also need to create custom statuses for Service Requests and Incidents. Just not sure how to implement this in the work flow.

Any assistance on this will be helpful.
