Reorder active tab in React Tab component

29 Aug 202324 minutes to read

We can able to prevent the changing of the active tab item on resizing the browser when overflow mode is popup by using the reorderActiveTab property. By default, the active Tab should be reordered when we click the tab items from the popup. If we set false to reorderActiveTab property the active tab item from the popup will not be reordered and an active item is highlighted inside the popup. The following code example depicts to prevent the reorder active tab item inside the popup.

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import {
  TabComponent,
  TabItemDirective,
  TabItemsDirective,
} from '@syncfusion/ej2-react-navigations';

const App = () => {
  let headertext;
  // Mapping Tab items Header property
  headertext = [

    { text: 'VB.NET' },

      technology, used by most websites to create visually engaging web pages, user interfaces
      for web applications, and user interfaces for many mobile applications. Web browsers
      can read HTML files and render them into visible or audible web pages. HTML describes
      the structure of a website semantically along with cues for presentation, making it a
