Event Tooltip

There are several approaches to showing a tooltip when hovering events.

The native tooltip

By default, the calendar shows the browser native tooltip when hovering over the event. This includes the times and title of the event, which does the job most of the times. For showing a custom text use the tooltip property of the data object. This tooltip is specific to every event. If you want to hide the native tooltip, you can set the showEventTooltip to false.

Fully custom tooltip

Setting the showEventTooltip to false gives room for a fully custom tooltip that can be implemented by using the onEventHoverIn and onEventHoverOut lifecycle events. With the help of the Mobiscroll popup you can show a custom tooltip that holds details, actions applicable to the event it is anchored to.

Showing a third party popup

There are cases when you are using a third party library, something like md-boostrap. For those cases, turn the browser native tooltip off with the showEventTooltip option and use the third-party tooltip accordingly. In case of md-boostrap, you can add the tooltip directive to the custom event template so that the library knows where and when to show the tooltip.
