only display one value in single choice list custom field in jira based other customfield value

Question

Hello,

Is there any way to limit the single choice list field(field A) value based on other custom field(field B)  value.

If the value of field B="1", in field A, there is only "value 1" displayed in the dropdown list.

if the value of field B="2", in field A, there is only "value 2" displayed in the dropdown list.

if the value of field B="2", all the values of field A will be displayed in the dropdown list.

Thanks and Regards

I don't do things with javascript because that way lies madness.  I can never recommend it because it always breaks.  For Behaviours, start at https://scriptrunner.adaptavist.com/latest/jira/behaviours-overview.html

Hello,

I choice option 2, I know I should write JS in field description or behaviour to achieve this function.

But do you have some examples how to only show the special value of customfield in dropdown list in javascript?

Thanks and Regards

Two options

*  Use a cascading select list - B as the main field, A as the secondary
* Code.  Hack some javascript into JIRA (horrid, ugly, unreliable and a pain to maintain), or find/write an add-on that provides the linked fields, or install Script Runner and use a Behaviour to do it
