I have a use case where I need some kind of cascaded multiselect, eg:
selecting team A and team D
I found some examples at https://library.adaptavist.com/search?page=1&products=jira&term=select but my use case does not seems to fit for any of the returned scripts.
Ideas anyone? Thanks!
There are no single fields (built-in or provided by any major plugins I know) that support this sort of data structure.
You could implement this in a couple of ways with Scriptrunner.
