Here is a simple example on how to try out the add-on component:

// Initialize a list with items
List<NamedObject> list = new ArrayList<NamedObject>();
NamedObject vaadin = new NamedObject(2L, "Vaadin");
list.add(new NamedObject(1L, "Java"));
list.add(vaadin);
list.add(new NamedObject(3L, "Bonprix"));
list.add(new NamedObject(4L, "Addon"));

// Initialize the ComboBoxMultiselect
final ComboBoxMultiselect<NamedObject> comboBoxMultiselect = new ComboBoxMultiselect<>();
comboBoxMultiselect.setPlaceholder("Type here");
comboBoxMultiselect.setCaption("ComboBoxMultiselect");
comboBoxMultiselect.setItems(list);
comboBoxMultiselect.setValue(new HashSet<>(Arrays.asList(vaadin)));
