Can the Cascader component support showCheckedStrategy #6313
Description
- I have searched the issues of this repository and believe that this is not a duplicate.
What problem does this feature solve?
只显示选中的子节点。
What does the proposed API look like?
同 antd 的 api，定义选中项回填的方式。Cascader.SHOW_CHILD: 只显示选中的子节点。Cascader.SHOW_PARENT: 只显示父节点（当父节点下所有子节点都选中时）。
