How can I show a specific custom field only when you select a line in another custom field?

[Jira Atlassiansson]

I want to filter options based on user selection so that when an option is selected from a dropdown list another dropdown list appears with only the options related to the value selected from the first dropdown. Is that possible?

Hi @Jira Atlassiansson  - Welcome to the Atlassian Community!

You can do that by creating a new custom field with the type of Select List (cascading). 

Then you can add values in the first field, and then values in the second field that only apply to the value in the first field.

Hi in similar line, would like to mandate one custom text field on one of the drop down selection.

Example - IF Impact is "Yes" then Impact details field need to be mandatory or throw the message as please update the Impact details
