Setting dimension in EJ2 TypeScript Tooltip control

8 May 20235 minutes to read

Height and width

The Tooltip can either be assigned auto height and width values or specific pixel values. The width and height properties are used to
set the outer dimension of the Tooltip element. The default value for both the properties is auto. It also accepts string and number values in pixels.

The following sample explains how to set dimensions for the Tooltip.

import { Tooltip } from '@syncfusion/ej2-popups';
import { Button } from '@syncfusion/ej2-buttons';

let tooltip: Tooltip = new Tooltip({
    width: '180px',
    height: '40px',
    content: 'This tooltip has 180px width and 40px height'
});
tooltip.appendTo('#target');

let button: Button = new Button({
    content: 'Show Tooltip'
});
button.appendTo('#target');

Scroll mode

When height is specified with a certain pixel value and the Tooltip content overflows, the scrolling mode gets enabled.

import { Tooltip } from '@syncfusion/ej2-popups';

let tooltipContent: HTMLElement = document.createElement("div");
tooltipContent.id = 'tooltipContent';
tooltipContent.innerHTML = "<b>Environmentally friendly</b> or environment-friendly, (also referred to as eco-friendly, nature-friendly, and green) are marketing and sustainability terms referring to goods and services, laws, guidelines and policies that inflict reduced, minimal, or no harm upon ecosystems or the environment.";

let tooltip: Tooltip = new Tooltip({
    width: '300px',
    height: '60px',
    content: tooltipContent,
    isSticky: true
});
tooltip.appendTo('#target');

The scrolling mode can best be seen when the sticky mode of the Tooltip is enabled. To enable sticky mode, set the isSticky property to true.
