Add tags to work items to categorize and filter lists
Tagging work items helps you quickly filter the product backlog or a work item query by categories that you define.
From Visual Studio Online or Team Web Access (TWA), open a work item and add a tag. Or, select from the list of previously assigned tags.
To add several tags at one time, type a comma between tags. Tags are case sensitive.
Tags that are listed in the tag bar are already assigned to the work item.
To unassign a tag, simply choose the x on the tag,.
Turn on filtering and choose a tag.
The list refreshes. Only those work items with the selected tag are displayed. Filtering the list disables add-a-backlog-item panel, stack ranking, and forecasting.
To apply a sub-filter, choose another tag.
To show all items, choose All or choose the filter icon to turn filtering off.
