The Summarize (SummarizeGrey) command available in the Gantt view toolbar displays the Summarized at Level dialog box, where the user can specify the level of detail (number of levels of descendant tasks) to display.


In order to summarize tasks, the user can also use the expand (ArrowRightSmall) and collapse (ArrowDownSmall) arrows displayed on the left-hand side of the Task’s Name in the Gantt spreadsheet.
