Spans edits

If the timeline has been configured for editing (horizontal moving, start and end date dragging), use the mouse to adjust the spans to suit your needs.

Dragging the span and changing the start or end dates updates the parent record.

Move the start or end dates to change the duration of the task.

Move the entire span horizontally to adjust the start and end dates but not the duration.
