Generate Similar Tabs Based on a Data Source
To generate similar tabs and views, bind the JavaScript 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 JavaScript 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.
