Looking for a way to populate drop-down "sub-fields" based on drop-down field choices

[blippincott]

I am looking for a way to populate the choices of a second drop-down field based on the choice of the first drop down field in an incident form. For example:

Drop-down 1:

Labeled: Category

Choices:Hardware, Software, Other

If "Hardware" is chosen:

Drop-down 2 would populate with:

Choices: PC, Laptop, Monitor, Printer (etc.)

If "Software" is chosen:

Drop-down 2 would populate with:

Choices: Windows, Office, (etc.)

If "Other" is chosen the user is given a text box to type something in.

Except for the Other text box functionality you should be able to do this out of the box w/ the  Select List (cascading) field. 

The add-on, Extension for Jira Service Desk has options to dynamically hide/display fields based on other field choices.

I do not see the Select List (cascading) field, is that something I have to enable?

These are the fields I have to choose from:

Looks like cascading select is not available for next Gen projects
