What is the use of data-toggle Attribute for Tooltips ?

The data-toggle attribute for tooltips in Bootstrap is used to specify the trigger event that activates the tooltip. When applied to an HTML element, such as a button or link, this attribute defines the event (e.g., hover, click, focus, etc.) that causes the tooltip to appear.

Syntax

<button data-toggle="tooltip" title="Tooltip text">Hover me</button>

Explanation: By including the data-toggle="tooltip" attribute on an element, along with the title attribute specifying the tooltip text, Bootstrap enables the tooltip functionality for that element. The data-toggle="tooltip" attribute tells Bootstrap to activate the tooltip when the specified trigger event occurs (e.g., when the user hovers over the element). This allows developers to easily add interactive tooltips to elements in their web pages.
