el-select下拉框添加横滚

根据引用内容和，在el-select标签中设置:popper-append-to-body="false"可以解决el-select下拉框跟随页面滚动的问题。然而，根据引用内容中的描述，这种解决方法会导致下拉框不可见，需要通过修改样式来解决。参考引用内容，可以使用样式穿透来实现添加横滚效果。可以在样式中添加如下代码：

.returformSelect .el-select-dropdown {
overflow-x: auto !important;
}

这样可以实现el-select下拉框的横滚效果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
