Ticket type option is mostly available with the ticket which describes the identification of the problem and reason of the ticket which is generated by the client. If you want to set some of the customization in the type which are there with the software or wants to add new type then this is right place.
Note: By default there are three ticket types:
- Issue: Issue will indicate that the ticket has certain issue or trouble.
- Question: Question indicates that ticket has a query that is associated with it.
- Bug: Bug indicates that there is a bug that is associated with the Ticket.
Issue ticket type cannot be disabled.
