You can bind any data object to Accordion items, by mapping it to
header and content property.
In the below demo, Data is fetched from an OData service using DataManager. The result data is
formatted as a JSON object with header and content fields, which is set to items property of Accordion.

import * as ReactDOM from "react-dom";
import { DataManager, Query, ODataV4Adaptor } from '@syncfusion/ej2-data';
import { AccordionComponent } from '@syncfusion/ej2-react-navigations';
const SERVICE_URI = 'https://services.odata.org/V4/Northwind/Northwind.svc/Employees';
class ReactApp extends React.Component {
accordCreated() {
new DataManager({ url: SERVICE_URI, adaptor: new ODataV4Adaptor })
.executeQuery(new Query().range(1, 4)).then((e) => {
let itemsData = [];
let result = e.result;
let mapping = { header: 'FirstName', content: 'Notes' };
for (let i = 0; i < result.length; i++) {
itemsData.push({ header: result[i][mapping.header], content: result[i][mapping.content] });
}
this.items = itemsData;
this.refresh();
});
}
render() {
return (<AccordionComponent ref={acrdn => this.acrdnInstance = acrdn} created={this.accordCreated}>
</AccordionComponent>);
}
}
