Anchor Elements
You can specify which elements (anchors) will render a tooltip.
To define which elements inside the kendoTooltip container will display a tooltip, set the filter property to а CSS selector string that matches these elements. For example, if you set filter="button.primary", the tooltip will appear on button elements with a class="primary" setting. If you set filter="div[data-url]", the tooltip will appear on div elements with a data-url attribute. By default, the filter property is set to the [title] selector which matches all elements with a title attribute.
To specify multiple types of elements as anchors, separate them with a comma—for example, filter="a[href],button[title]". The default tooltip template will render only the content from the title attribute of the anchor. You can change this behavior by applying the content templates.
You can render a header title for the Tooltip content by binding the titleTemplate property to a TemplateRef object.
