This sample explains you about the custom template support of the Dropdown Tree. When you click the checkbox, the selected items will be visualized based on the given custom template.
The Dropdown Tree control allows the user to select more than one value while enabling the checkbox or multi selection support. The user can visualize the custom template instead of the selected item texts in the Dropdown Tree by enabling the mode type as Custom. User can also customize the given template by using the customTemplate property. In this demo, the Dropdown Tree is populated with the checkbox and custom template feature.
