The DropDownButton is a button that opens a drop-down menu. The button displays a text and an icon.
Menu items can be specified in the items or dataSource properties. Use dataSource if data is remote or should be processed. To customize menu items, implement an itemTemplate.
The DropDownButton stores the most recent selected menu item if you set the useSelectMode property to true. In this case, the button uses the selected item’s text and icon.
You can implement a dropDownContentTemplate to replace the drop-down menu with custom content.
To track and handle events, use the onButtonClick, onItemClick, and onSelectionChanged event handlers.
