The allowEventOverlap property (boolean) enables or disables JavaScript Scheduler event overlap protection during drag and drop operations. It affects time range selecting, event moving, and event resizing. This property does not affect existing events.
If the value is set to false, the Scheduler will disable the drag and drop shadow (the color will change to red) if the target position overlaps an existing event.
