fullCalendar - Event title and detail

Question

I'm using the pretty fullCalendar jQuery plugin.

I'd like to be able to have a title AND a detail on each event as in the screenshot below:

Here the details are the participants for each session. (overflow hidden on the detail)

If you want to set the title use eventDidMount instead of eventRender

eventDidMount:function(info){
   info.el.title="---- YOUR TEXT----"
}

For anybody having this issue in Angular 8:

eventRender: function(event, element)
{ 
    (element as Element).querySelector('span.fc-title').append("
" + event.description); 
}
