Customize Tab Contents and Appearance
You can initialize a tab’s contents (text, icons and badges) with values from underlying data objects. This example demonstrates this technique.
Use the drop-down editors on the right to change the component's orientation, styling mode, and icon position.
You can also specify an item template (itemTemplate) to customize tabs.
Configure Overflow Behavior
The Tabs component stretches to fit its container if you do not specify the component's width. When the total tab width exceeds the component’s width, navigation buttons appear. A user can click these buttons to scroll through the tabs. Use the showNavButtons and scrollByContent properties to control this behavior.
