Selection
This demo processes tab selection and uses SelectBox and MultiView components to emulate page content. Both these components are bound to Tabs, and vice versa.
You can use the following properties to configure selection:
-
selectedIndex
The index of the selected item. -
selectedItem
The selected item. -
selectedItems
An array of selected items. -
selectedItemKeys
An array of selected item keys. -
selectionMode
Specifies whether the component allows users to select only a single item or multiple items. -
onSelectionChanged
A function that is executed when a collection item is selected or selection is canceled.
Feel free to share demo-related thoughts here.
