How to implement validation for Custom Field on Change Request Issue Type
Is there any way to implement Custom Validation if the user gives wrong input on textbox field. Below is the example for custom field called as "Interested Parties" where I need the user to give email addresses separated with comma. The emails are being sent out via JIRA Automation Rule. But I need to validate if the user is giving email address instead of any other input.
And also want if I can have a textbox with combination of JIRA users email address as a drop-down list and custom text where user can enter email address separate with comma.
