Creating a grid fo attributes in a work item section that can be "incremented" by the push of a button
Accepted answer
Karen,
It is technically possible to create your own work item editor presentations and even custom attribute types. For a full implementation of an editor presentation you need to implement the plugins for the Eclipse client as well as the plugins for the server side, including the Web UI. See https://github.com/jazz-community/rtc-statushistory-presentation as an example for the Web/server part.
I don't know the details of implementing your own custom attribute types, but I know this has been done.
I would suggest to stay away from doing of the things mentioned above. It is hard to do, not well documented and needs to be maintained and migrated.
There used to be a team that created custom extensions, but that does not exist any more.
