我解决了这个问题，我把答案范围内帮助其他用户有同样的问题：在引导程序中，我们可以使用该事件来设置 overflow：inherited ，但如果您的父容器上没有css属性，这将工作。

I solved myself this and I put the answer in scope to help other user that have same problem : We have an event in bootstrap and we can use that event to set overflow: inherited but this will work if you don't have css property on your parent container.

$('.table-responsive').on('show.bs.dropdown', function () {
     $('.table-responsive').css( "overflow", "inherit" );
});

$('.table-responsive').on('hide.bs.dropdown', function () {
     $('.table-responsive').css( "overflow", "auto" );
})

这是小提琴

and this is the fiddle

info： 在这个小提琴的例子工作奇怪，我不知道为什么，但在我的项目工作很好。

info: In this fiddle example works strange and I'm not sure why but in my project works just fine.
