Adding Columns
Structure allows you to add columns to view key information about your work items at a glance. You can customize what information is available by adding new columns or changing the arrangement of your columns.
By default, the following columns are visible in a structure:
Work Item Key Column - Displays the work item key
Summary - Displays the work item summary (This is also where your work item hierarchy is visible – the summary for child work items are indented relative to their parent work items.)
Status - Displays the work item status
Assignee - Displays the work item's assignee
Adding New Columns
To add new columns, click the + sign to the far right of the column headers.
