TreeView control allows you to set tooltip option to tree nodes using the tooltip property. The following code example demonstrates how to set tooltip for TreeView nodes.
import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { TreeViewComponent } from '@syncfusion/ej2-react-navigations';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
export default class App extends React.Component {
constructor() {
super(...arguments);
// Data source for TreeView component
