Show and Hide the Tooltip

To show and hide the Tooltip in response to certain events, specify the showEvent and hideEvent properties. These properties can accept multiple events at once as well as an object.

To hide the Tooltip when a user clicks outside its borders, use the hideOnOutsideClick property.

Customize and Animate the Tooltip

Assign the Tooltip's content in the HTML markup. Alternatively, you can use the content template to customize the Tooltip's content.

If you need to position the Tooltip at a certain side of the target element, specify the position property.

To animate the Tooltip, declare the animation object. In this object, specify the show and hide fields.
