Only allow specific groups to create this issue type

[Allen Chun]

I have a custom issue type called Idea and I only want users under this group can create this issue. 

How can I achieve this? Is it possible to set this permission per project?

Hi Allen

The out-of-the-box Jira way to do this is using a different workflow for the issue type you want to restrict and add a validator on the create transition allowing that group only to create the issue.

Unfortunately other users will be able to pick the issue type as well because conditions on the create transition are not supported.
