Question

我最近下载了Wox，这是Windows的另一种搜索方式。其搜索会自动显示为下拉菜单。设置中没有办法将其更改为“下拉”，而不是下拉。我在任何地方都找不到这个问题，但是制造商回答说，有关外观更改的问题，以编辑基本主题文档。我仔细阅读了文档，发现在保管箱掉落时似乎找不到切换的地方，但是我也只有非常基本的编码知识。我试图搜索如何在线执行此操作，但似乎找不到任何东西。标记文件如下。我有什么可以改变的，以使其掉落吗？

Answer 1

以下是更改ComboBox的 ControlTemplate 的MSDN示例：https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/combobox-styles-and-templates

有趣的部分是弹出窗口：

<Popup x:Name="Popup"
             Placement="Bottom"
             IsOpen="{TemplateBinding IsDropDownOpen}"
             AllowsTransparency="True"
             Focusable="False"
             PopupAnimation="Slide">

将展示位置更改为顶部应该会有所帮助。
