Dynamic population of a custom field on selecting value from other custom field.

[Ruchika T]

I have few custom fields of type drop-down in the Create Issue page.

On change of custom field 1, based on the value selected, I want to populate custom field 2 and so on.

Can anyone help me on how to achieve this.

Thanks in Advance for the help!!!

Most simple option is to swap custom field 1 and 2 for a "cascading select".

The more complex options involve add-ons to enable this sort of behaviour.

Requirement is to populate these drop down dynamically. On selection of a value from dropdown1 i'll fire a query to get corresponding values for dropdown2 and dynamically populate it with these values.Can I still use cascading select for dynamic values. If yes, can u please provide some sample code on how to do it. I am using Jira version 7.

Yes, that's exactly what a cascading select does. You select an item from the left hand drop-down and that determines the options listed in the second drop-down. You don't need any code at all.

Thanks Nic. But in cascading select what I could see, we beforehand configure static data in the list.Say, for value "A" in dropdown1, I configured values "A1","A2","A3" etc in the drop down2. In my case, I don't have data for dropdown2 beforehand to configure. I'll only get this data from some code which will fire some query in the database and based upon these values which I get will populate the dropdown2. How can this be achieved in Jira.

Oh, hang on, you're saying you don't have the values for the options yet? I think I've misunderstood part of the question. The answer about add-ons definitely applies then. JIRA's options are dynamic (selected by current data for some fields), but you do have to pre-define them before they can be used. >some code which will fire some query in the database and based upon these values which I get will populate the dropdown2 That's where add-ons apply - you will need to find or write an add-on to do that. You're asking JIRA to retrieve a set of values and then store what the user selects, with no previous knowledge of that data. I'd take a look at the database fields available in the marketplace first, but I'm pretty sure you're going to have to write something.
