我有一个ListBox控件，在那里我有一些自定义下拉菜单的自定义项（我几天前的问题-How to show a ListBox item outside the ListBox control and over all other controls on Item click）。
现在，我有一个新的问题，我附上一个视频剪辑。所以，我想我的底部项目的行为，作为一个以上的点击项目。因此，当我点击底部的项目时，我希望上面的项目向上移动，以便显示最后一个项目的下拉菜单。你可以看到，当我点击上面的项目，他们改变了大小，并移动底部的项目，以显示下拉菜单。同样的原则也适用于其他自定义列表框，但这里没有，因为这些自定义项（仅在这里）。请看我发的视频。您可以找到定义项目的数据模板代码。
