How to modify the values of a field according to another field

[Aexandra Auvrignon]

I'm working on JSM and I'd like to be able to modify the values in the drop-down list for a field called: "Option" which is a Single-choice drop-down list, depending on the value in the "Incident" field (of the same type).

I've seen that you can use the plugging ScriptRunner for Jira but it's not an option for me as this extension is not free. Do you know of any other way? I've tried setting a rule with advanced field editing but I can't get it to work.

Thank you

Hi @Aexandra Auvrignon and welcome to Community!

This is exactly what Cascading fields are designed for:

Once you’ve created one, you can configure it so that the second dropdown depends on the value selected in the first:

Hope this helps!

Hello, thank you for your reply.

I want to link two existing fields. Is it possible to change the type of my second field to cascading field (i don't think so)?

If not, is there another way to modify the values in the drop-down list , depending on the value of the first field.

It's unfortunately not possible to:

• change an existing custom field type (see the related feature request: Change the Type of a Custom Field)
• make a dropdown list depend on another one (without a third-party paid app)

The only out-of-the-box solution is to switch to a cascading field.

Welcome to Atlassian Community!

This can be achieved using Cascade Custom Field option.

Yes, you are correct! We cannot change the Custom Field type once created. We can only select it while creating.

We can use automation to change the values of a custom field based on option selected in another field.

But if you're looking to dynamically change values in drop down menu based on another field value then going for cascading field option is suggested
