Users can also add certain default checklist items for a work item type by going to "Work item checklist" settings hub, or by clicking the gear icon on the checklist group on work item form.
These default checklist items would show up for all the workitems of that work item type in the current project. The state of these default items would still be maintained at each work item's level. For eg. In the screenshot above, "Unit tests done" and "Functional tests done" are 2 default checklist items which would show up in each "Bug" work item. But if a user checks "Unit tests done", it would only be checked for that particular work item.
Default items are not sortable or removable from work item form. Users can do that via tha settings hub.
