Overview

The TabPanel UI component includes both the Tabs and MultiView components. The TabPanel automatically synchronizes the selected tab with the currently displayed view (and vice versa).

To get started with the DevExtreme TabPanel component, refer to the following step-by-step tutorial: Getting Started with TabPanel.

Generate Similar Tabs Based on a Data Source

To generate similar tabs and views, bind the TabPanel to data (using the items or dataSource property). Both these properties can work with local arrays, but dataSource also accepts a DataSource object. You can use this object if you need to process the local array or fetch the array from a remote data source. In this demo, the dataSource property is set to a local array.

Each object in the items[] or dataSource array can contain predefined fields, such as title or icon (see the items[] section for the full list). The TabPanel automatically recognizes these fields and creates the default tab and view appearance based on them.

Customize Tab Contents and Appearance

You can initialize tab contents (text, icons and badges) with values from underlying data objects.

Use the drop-down editors on the right to change tab position, styling mode, and icon position.
