"Issue Type" drop-down list custom field

[Egle K.]

I would like to have custom field that includes drop-down list consisting of all 'issue types' that are available in my JIRA instance (something like "Project Picker" that already exist).

any ideas how to create such CF?

I didn't find any add-on which allows to create such custom fields. Maybe anyone else will know.

In case, no such add-on exists, you have to create new custom field type. There is some old tutorial here:

https://developer.atlassian.com/server/jira/platform/creating-a-custom-field-type/

I suggest you to check source code of 

com.atlassian.jira.issue.customfields.impl.AbstractSingleFieldType

and

com.atlassian.jira.issue.customfields.impl.ProjectCFType

I'd start with these to understand how CF types work. Then try to follow the steps described in tutorial and let me know where you got.
