The DropDownBox uses other UI components to render items. Use the contentTemplate to embed a UI component such as the List or the TreeView. In this case, items are displayed in accordance with the configuration and functionality of the embedded UI component.
If you need to update UI component items, reassign the items array as shown in the following example:
You can use the dataSource property instead of items. It accepts the DataSource object whose underlying stores include API that allows you to update individual items without reassigning the entire item collection.
The following types of the specified value are available.
- Assign a string containing the name of the required template.
- Assign a jQuery object of the template's container.
- Assign a DOM Node of the template's container.
- Assign a function that returns the jQuery object or a DOM Node of the template's container.
