Content in React Tooltip component

A text or a piece of information assigned to the Tooltip’s content property will be displayed as the main text stream of the Tooltip. It can be a string or a template content. If the content property is not provided with any specific value, then it takes the value assigned to the title attribute of the target element on which the Tooltip was initialized. The content can also dynamically be assigned to the Tooltip via AJAX.

Template content

Any text or image can be added to the Tooltip, by default. To customize the Tooltip layout or to create your own visualized element on the Tooltip, template can be used.

Refer to the following code example to add formatted HTML content to the Tooltip.
