去掉 popover props 中的 getPopupContainer={trigger => trigger.parentNode} 试试

但是我还需要popover滚动跟随

[AshoneA]

Use getPopupContainer={trigger => trigger}.

Use getPopupContainer={trigger => trigger}.

popover可以了！但是popover里面的select展示不开了，并且select我也想跟随滚动

[AshoneA]

对 Select 也用 getPopupContainer={trigger => trigger}.

我这个demo，用trigger.parentNode会使滚动条自动滚到顶部，不是trigger.parentNode的原因~

@zhangzhi93 把 Modal 内容区域高度调高一点。

@zhangzhi93 把 Modal 内容区域高度调高一点。

和modal高度没关系吧，我找找合适的节点放select吧，popover用getPopupContainer={trigger => trigger}是可以了
