Can I prevent events with conflict time?

Question

How can I prevent events with conflict time? Is there any variable to set up?

Answer 1

Add custom property in the event object overlap:false for example your event object will be

                 `{
                    title:'Event',
                    start: '2017-01-04T16:30:00',
                    end: '2017-01-04T16:40:00',
                    overlap:false
                  }`

Now override selectOverlap function,

selectOverlap: function(event) {
    if(event.ranges && event.ranges.length >0) {
      return (event.ranges.filter(function(range){
          return (event.start.isBefore(range.end) &&
                  event.end.isAfter(range.start));
      }).length)>0;
    }
    else {
      return !!event && event.overlap;
    }
  },

It will not let the another event to override the already placed event.
