重写 Cascader
Rewrite Cascader

项目描述/Project Description

部分 antd 组件可以通过重构复用现有组件统一提升其性能以及改进包尺寸。在 v4 中，Select 组件底层已经为全键盘以及无障碍做了技术支持。因而类似的 Cascader 组件也可以借此获得相关能力。
Some antd components can be refactored and reused to improve their performance and package size. In v4, the base of the Select component has provided technical support for the full keyboard and accessibility. Therefore, similar Cascader components can also be used to obtain related capabilities.
