JavaScript/jQuery DropDownButton - items
The items array can contain:
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the keyExpr and displayExpr or itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
dropDownButtonInstance.option('items', newItems);As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
