React Event calendar Drag-and-Drop Task Presets

Use external draggable events to create preset tasks that people can quickly copy and spawn events from. A great example is a car wrapping shop where different jobs need to be set up depending on the type of vehicle.

Print a list of predefined tasks and initialize them as draggable elements. Enable externalDrop for the calendar and set up the predefined event skeletons for the draggable component.

Whenever there is more information to be captured, like detailed task notes, customer information, the name of the technician... you can trigger a popup with the task form in the onEventCreate lifecycle event. For failed drops (trying to schedule a task during lunch breaks or weekends) the onEventCreateFailed event will be triggered.

Drag preset task templates from an external list onto a event calendar — a popup form captures task details and technician at drop time.
