eventResourceEditable

Determines whether the user can drag events between resources.

The default value is inherited from the master editable flag, which is false by default.

You must enable the interaction plugin before using this setting. <a href='editable' class='more-link'>See code samples on the editable article</a>

A variation of this property called resourceEditable can be set on an Event Object for more granular control:

var calendar = new Calendar(calendarEl, {
  initialView: 'timelineWeek',
  resources: [
    // resource data...
  ],
  editable: true, // event resources editable by default
  events: [
    // event data...
    {
      title: 'my event',
      start: '2016-01-01',
      resourceEditable: false // resource not editable for this event
    }
  ]
});

A similar technique can be used on Event Source Objects.

Preventing date changes, but allowing resource changes

If you'd like to allow the user to drag-n-drop an event to a different resource, you can set the master editable flag to false, but override it specifically for event resources:

var calendar = new Calendar(calendarEl, {
  initialView: 'timeline',
  editable: false, // don't allow event dragging
  eventResourceEditable: true // except for between resources

  // resource and event data...
});
