Also, can hierarchies be created in work items?
Have seen Related items.
This version does not support custom-defined buttons, checkboxes, or custom controls. Neither it supports custom hierarchies; the only two hierarchies are Area Path and Hierarchy Path; for those we have a special control type called WorkItemClassificationControl.
Could you clarify what do you mean by calling work items?
Thanks
Thanks.
Unfortunately we do not support this scenario in this version - all lists of values used in the work item type XML are static lists of strings. In some cases you could try an approach with global lists (i.e. defining so called "global list", which will be included in the list of allowed values, and update that global list on a regular basis with the latest information).
