ListView component supports Nested list. For that, we should define child property for the nested list in array of JSON.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { ListViewComponent } from '@syncfusion/ej2-react-lists';
function App() {
    // define the array of Json
    let arts = [
        {
            text: "Asia",
            id: "01",
            category: "Continent",
            child: [
                {
                    text: "India",
