Please refer screenshot attached
DayPilot includes a built-in callout named "bubble". See more here: https://doc.daypilot.org/calendar/event-bubble/
You can map it to event click action by setting eventClickHandling config property to "Bubble" (Angular):
config: any = { eventClickHandling: "Bubble", // ... };
Thanks for answer, do you have any example for bubble callout in angular 6
