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 React from "react";
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';
function ReactApp() {
let acrdnInstance;
const 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] });
}
acrdnInstance.items = itemsData;
acrdnInstance.refresh();
});
};
return (<AccordionComponent ref={acrdn => acrdnInstance = acrdn} created={accordCreated}>
</AccordionComponent>);
}
