If you want each tab and view to have differently structured content, define individual templates. To do this, assign an array of objects to the items[] or dataSource property and specify the tabTemplate and template properties in each object. This use case is illustrated in the following tutorial: Getting Started with TabPanel.
Use the following properties to configure user navigation between tabs:
-
swipeEnabled
Defines whether to switch between views with a swipe gesture. -
loop
Specifies whether to loop views. -
animationEnabled
Specifies whether to animate transition between views.
You can switch the checkboxes below the TabPanel to change the loop, animationEnabled, and swipeEnabled property values.
