How to show read only calendar

Yes, you can disable event moving using the eventMoveHandling property:

{
  eventMoveHandling: "Disabled",
  // ...
}

Perfect. it works like a charm.

Another question: I have a long description for the eevent that I want to show inside the event UI, which seems impossible in the current event box, what do I want when double click on the event box opens up a popup and there it will show the description of this event? Any idea how I can implement this?
