Remove parent checkbox in React TreeView component

28 Feb 202512 minutes to read

By enabling the showCheckBox property, you can render check box before each node of TreeView. However, some application needs to render check box in child nodes alone. In such case, you can remove the check box of the parent node by customizing the CSS.

import * as ReactDOM from 'react-dom';

import { TreeViewComponent } from '@syncfusion/ej2-react-navigations';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
function App() {
    // Data source for TreeView component
    let Countries = [
        { id: 1, name: 'India', hasChild: true, expanded: true },
        { id: 2, pid: 1, name: 'Assam' },
        { id: 3, pid: 1, name: 'Bihar' },
        { id: 4, pid: 1, name: 'Tamil Nadu' },
        { id: 6, pid: 1, name: 'Punjab' },
        { id: 7, name: 'Brazil', hasChild: true },
