描述

  • I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

Currently, in cascader component, the user has to press the down arrow twice to select the first option (once to open the cascader options list and second to select the first option). However, if the first option is ative by default then it will reduce the need of pressing down key for selecting the first option.

What does the proposed API look like?

The Select component alreadty has a defaultActiveFirstOption prop. We can use the same syntax for the cascader component as well.

研究方向
Examine the existing Select component's implementation of the `defaultActiveFirstOption` prop in the Ant Design codebase, particularly the files under `components/select`. Then apply the same logic to the Cascader component, likely located in `components/cascader`. Review the Cascader's dropdown logic in `Cascader.tsx` and its related hooks to integrate the prop. Ensure the prop matches the existing API pattern and handles keyboard navigation correctly.
