How to show customized field only if the prior field is filled?

Question

I'd like to show a custom field called FIELD A. An other custom field called FIELD B should be hidden. If the customer used the FIELD A, then should appear also the FIELD B.

FIELD A = "Select List (cascading)"

FIELD B = "Select List (cascading)"

What do I need to do?

It's possible to achieve this using an add-on as scriptrunner for example. With the functionalities Jira already has, there is no configuration that makes fields get hidden and only appears if another option is selected.
We found a thread in community that may help you achieve this:

Thank you Angelica for your input.

Please don't misunderstand me, but I think that's not true.

2 years ago, I worked the first time with the Jira Service Desk and it was possible, but I didn't implement it. Now I need it and I forgot, how to reproduce it.

Best regards
Aleksandar

Hello Aleksandar,

Currently, it's not possible to hide/show fields based on other fields. We have a feature request suggesting the implementation of this ability:
