您好我正在尝试使用一些处理显示和表单提交的jQuery进行主要的CSS下拉。我正在努力的一件事就是让下拉列表不会推动其他元素。欢迎任何其他建议是我的代码（我知道不应该使用表格，但必须在传统的UI中使用它，所以请耐心等待）

如果您从菜单的正常流程中取出菜单，它将不会推动任何其他元素。
您可以通过添加position:absolute;或使用float:left或float:right来完成此操作。这些命令会从流的其余部分中删除您的菜单，允许它在其他元素的上方或下方。
但要注意float，因为如果你浮动其他元素，它们就会开始相互碰撞。在这种情况下，您应该使用position:absolute。如果您需要移动菜单的位置，请使用left: 100px; top:200px等
