我正在开发smartGwt项目，我开发了简单的slectedItem下拉菜单。这个下拉菜单不会显示任何选项，这是多个选择下拉菜单。下面是我的代码SlectedItem下拉列表不显示值
final Window winModal = new Window();
winModal.setWidth(700);
winModal.setHeight(400);
winModal.setAutoSize(true);
winModal.setTitle("Schedule");
winModal.setShowMinimizeButton(false);
winModal.setIsModal(true);
winModal.setShowModalMask(true);
winModal.centerInPage();
DynamicForm form = new DynamicForm();
form.setHeight100();
form.setWidth100();
form.setPadding(5);
form.setLayoutAlign(VerticalAlignment.BOTTOM);
SelectItem selectItemMultiplePickList = new SelectItem();
selectItemMultiplePickList.setTitle("Select Multiple");
selectItemMultiplePickList.setMultiple(true);
selectItemMultiplePickList.setMultipleAppearance(MultipleAppearance.PICKLIST);
selectItemMultiplePickList.setValueMap("Cat", "Dog", "Giraffe", "Goat", "Marmoset", "Mouse");
form.setFields(selectItemMultiplePickList);
winModal.addItem(form);
winModal.show();
我的下拉窗口小部件展示，但没有显示任何值，内部下拉提前

你可以试试'winModal.addMember（form）;'而不是'winModal.addItem（form）;'？ – RAS
我刚刚测试过你的代码，它的工作原理是'GWT'：'2.7.0'和'SmartGWT'：'6.0'。 SelectItem展开并显示所有值。 https://i.imgur.com/1tW71f8.png – pleft
