Custom Event Sort Order

When rendering events, the default logic determines the order:

  • All-day events are placed at the top
  • Non-all-day events follow, sorted by their start times
  • Events with the same start time are ordered alphabetically by their title

The order property of the event data can be used to override the default ordering. The order property takes precedence over the default rules. If two events have the same order value, the default rules apply. For a more advanced order logic, the eventOrder option can be used which expects a function that compares two events and returns an order (-1 or 1).
