I am using fullcalendar in one of my Rails projects to render events on calendar.
The jsfiddle shows the scenario.
I am able to adjust the width but it doe
Take a look at this fiddle: http://jsfiddle.net/100thGear/jRFYE/
I used the eventRender callback to alter the offset of the next event(s). Hope this helps and gives you an idea of how to proceed.
Why don't you use the className attribute of the event object to set this? You could set the width in the CSS class you are passing to this attribute.
