Hi, i have Jira server and ScriptRunner, i want to modify create issue screen.

I want to insert custom field "Filtre projet Support" on top in this screen.
And if "Filtre projet Support" is check, i want to restreint Project field (yellow)
Is-it possible with ScriptRunner ?
I must use "Fragment" and Behaviours ?
And what kind of "Fragment"?
Best regards
Fred
