@leemove @vthinkxie I made a PR #5650 to fix this issue

Hi @leemove @DepickereSven 按照 ant design 设计规范，在多选模式下是没有下拉箭头的，在 9.x 之后同步了 antd 4.x 的设计规范，因此多选箭头被移除了，这是在预期中的，不是一个bug

感谢关注

By ant-design are you referring to this library https://github.com/ant-design/ant-design/?

Because when I look in their docs I find the following:

So for multi-select and tags is by default on false. But it's possible to set the showArrow on true so you can see it.

Like you can see in the following example the icons work in multi and tag mode.
