Size modes Size Mode for Syncfusion EJ2 TypeScript Controls

10 May 20239 minutes to read

An application that is designed to be accessed through a web browser on various devices, including desktop computers and mobile devices, may have a distinct layout or user interface on a mobile device compared to a desktop computer to better suit the smaller screen size.

Syncfusion JavaScript controls support both touch (bigger) and normal size modes. Touch mode creates a responsive design for mobile devices by adding the e-bigger class, which enhances interactions, visibility, and the overall experience.

Size mode for application

The user can enable touch mode (bigger) for the entire application by adding the e-bigger class to the body element in the index.html file as follows:

  <body className="e-bigger">
    ...
  </body>

Size mode for a control

The user can enable touch mode (bigger) for a control by adding the e-bigger class to the div element that contains the control. Another way of enabling touch mode is by adding the e-bigger class using the available cssClass property of the control.

import { Button } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize the Button component.
let button: Button = new Button({ content: 'Button' });

// Render initialized button.
button.appendTo('#element');

Change size mode for application at runtime

The user can change the size mode of the application between touch and normal (mouse) mode at runtime by adding and removing the e-bigger class. The following steps explain how to change the size mode of an application at runtime:

import { Button } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';
import { Calendar } from '@syncfusion/ej2-calendars';

enableRipple(true);

// Initialize the touch button.
let touchButton: Button = new Button({ content: 'Touch Mode' });
touchButton.appendTo('#touch');
touchButton.element.onclick = (): void => {
    document.body.classList.add('e-bigger');
}
// Initialize the mouse button.
let mouseButton: Button = new Button({ content: 'Mouse Mode' });
mouseButton.appendTo('#mouse');
mouseButton.element.onclick = (): void => {
    document.body.classList.remove('e-bigger');
}
let calendarObject: Calendar = new Calendar();
//Render initialized calendar.
calendarObject.appendTo('#calendar');

Change size mode for a control at runtime

The user can change the size mode of a control between touch and normal (mouse) mode at runtime by setting the e-bigger CSS class.

import { Button } from '@syncfusion/ej2-buttons';
import { enableRipple } from '@syncfusion/ej2-base';
import { Calendar } from '@syncfusion/ej2-calendars';

enableRipple(true);

// Initialize the touch button.
let touchButton: Button = new Button({ content: 'Touch Mode' });
touchButton.appendTo('#touch');
touchButton.element.onclick = (): void => {
    let controls = document.querySelectorAll('.control');
        for (let index: number = 0; index < controls.length; index++) {
            controls[index].classList.add('e-bigger');
        }
}
// Initialize the mouse button.
let mouseButton: Button = new Button({ content: 'Mouse Mode' });
mouseButton.appendTo('#mouse');
mouseButton.element.onclick = (): void => {
    let controls = document.querySelectorAll('.control');
        for (let index: number = 0; index < controls.length; index++) {
            controls[index].classList.remove('e-bigger');
        }
}
let calendarObject: Calendar = new Calendar();
//Render initialized calendar.
calendarObject.appendTo('#calendar');
