Calendar events are displayed on top of each other when at the same time in

Hi,

I am using a calendar in my application and when I have multiple events at the same time or at times that are close (like 12:05 and 12:07) the event are displayed on each other in the week and day view. In the demo (
https://demo.vaadin.com/calendar
) for the calendar the events are displayed next to each other if you have more than one at the same time.

What am I missing here ? Would that be the css ?

We are using Vaadin 7.6.6.

Thanks,

Simon
