You could use filtering events, Im showing you an example on how I hide events that are appointments in my application (I'm only using month view), obviously you need to attach the event in the dropdown.
scheduler.filter_month = function(id,event){ //Im only hiding them in the month view, you can check on the link I psoted the way to do it in allv iews
if(event.is_appointment == 1) //Im using a custom event with the property is_appointment
return false;
}
scheduler.updateView();
You can find more info on Scheduler Filtering
