ej.base.enableRipple(true);

// Initialize the Tooltip Rating control.
var rating = new ej.inputs.Rating({ showTooltip:true, value:3 });

You can use the tooltipTemplate tag directive to specify a custom template for the tooltip of the rating. The current value of the rating will be passed as the value property in the template context when building the content of the tooltip. This allows you to include dynamic information about the rating in the template.

index.js
index.html
styles.css
ej.base.enableRipple(true);

// Initialize the Show Tooltip Rating control.
var rating = new ej.inputs.Rating({ showTooltip:true, value:3, tooltipTemplate: '#tooltipTemplate' });

// Render initialized Rating.
rating.appendTo('#rating');

You can customize the appearance of the tooltips using the cssClass property of the rating control and by defining the custom styles for tooltip elements like the below example.

You can find more information about customizing the appearance of the tooltip in the Tooltip Customization documentation.
