Template in React Spinner component

You can use custom templates on the Spinner instead of the default Spinner by specifying the template in the setSpinner method.

The following steps explains you on how to define template for Spinner.

  • Import the setSpinner method from ej2-react-popups library into your index.tsx as shown in below.
import { setSpinner } from '@syncfusion/ej2-react-popups';
  • Pass your custom template to the setSpinner method like as below.
// Specify the template content to be displayed in the Spinner

setSpinner({ template: '<div style="width:100%;height:100%" class="custom-rolling"><div></div></div>'});

You should set the template to the Spinner before creating the respective Essential JS 2 component. Also,until we replace setSpinner template, the further Essential JS 2 component rendering is created with given template only.

  • Now, render the Essential JS 2 component. It’s render the Spinner with the template specified in the setSpinner method.

In the below sample, we have rendered the Grid component with custom Spinner using setSpinner method. You have to define the styles for the template in index.html.
