One Event with multiple resources

You need to create a special entry for each of the event x resource combination.

You can use "joint events" feature to link them together so they will be moved and resized together:

Example:

dp.events.list = [
 { name: "Event", id: "5.1", resource: "R1", join: 5,  .... },
 { name: "Event", id: "5.2", resource: "R2", join: 5,  .... },
  ...
];
