Appointments can be grouped by resources. This demo declares a single resource—Priority. Refer to the following demo for more information about resources and their configuration: Resources.
When appointments are grouped by resources, you can additionally group them by date first. To do this, set groupByDate to true. You can also use the same property for individual views. Note that Scheduler groups appointments by date when the view's groupOrientation is "horizontal" only.
In this demo, you can use the switch below the Scheduler to change the value of groupByDate.
