Question

我在表单布局中使用原生选择，如下所示：
您可以看到我的原生选择内容过于冗长：

  accountType = new NativeSelect("Account Type:");
    accountType.setRequired(true);
    accountType.setNullSelectionItemId("--Select--");
    accountType.addItem("Regular Savings");
    accountType.addItem("Silver Savings");
    accountType.addItem("Gold Privilege");
    accountType.addItem("Advantage Premium Savings");

    idProof = new NativeSelect("ID Proof:");
    idProof.setSizeFull();
    idProof.setRequired(true);
    idProof.setNullSelectionItemId("--Select--");
    idProof.addItem("Arms License issued by State/Central Government authorities");
    idProof.addItem("Bank Pass Book with photograph issued  or its susidiaries or Nationalised Banks");


    FormLayout fLayout = new FormLayout(accountType,idProof);

然后我将此formlayout添加到horizontalLayout

 HorizontalLayout hlayout = new HorizontalLayout(fLayout,fLayout2);

但我的idProof下拉单元格内容扩展了父级的宽度如何强制下拉列表保留在父布局内，无论内容宽度是什么？

Answer 1

idProof.setWidth(20, Unit.EM);

当然，你可以选择你想要的任何宽度，而且，不再需要idProof.setSizeFull（）。
