conditional custom fields

[Ridhy]

We are creating a custom screen for Change Management Requests and we have several custom fields.  We do not want to display all of the fields on the first screen; however they should be triggered based on responses selected in previous fields.  For Example: If Training is needed the user would select "Yes" and it should prompt for additional questions to be answered; however these other fields should not be displayed in the general create issue screen.  How can this be achieved within JIRA Core Server?

Hacky javascript, or use the Behaviours functions built into the Script Runner add-on (also javascript, but using the add-on means you don't have to maintain the js yourself)

Thank you Nic for the suggestion; however I'm not too familiar with Javascript is the script runner add-on user friendly or do you need Javascript knowledge to use it?

It's hard work with javascript, and even harder to get right.  Behaviours does make it a lot easier
