我在 GWT 中使用SuggestBox来创建一个带有很好建议列表的文本框，如下所示：

public void onModuleLoad() {
    MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();  
    oracle.add("Cat");
    oracle.add("Dog");
    oracle.add("Horse");
    oracle.add("Canary");
    SuggestBox box = new SuggestBox(oracle);
    RootPanel.get().add(box);
    }
}

问题是我希望建议列表出现在文本框的顶部，而不是底部。

有没有办法做到这一点？

如果没有，GWT 中是否有任何替代 SuggestBox 的方法？（我成功地配置了 jQuery 的自动完成小部件以显示在文本框的顶部，但将其与 GWT 集成似乎既不优雅也不高效......）

谢谢！

I don't think that there is any built-in way to do that, but I think it could be done with a little bit of work. SuggestBox has a constructor that takes a SuggestionDisplay as parameter. So you could subclass DefaultSuggestionDisplay and override its showSuggestions() method to display the popup where you want.
