希望在移动端也能看到菜单

iissnan大神你好，非常感谢你贡献的主题！
我的博客使用场景是类似说明文档，文章有严格的排版结构，Next的自动toc很棒，但我希望在移动端也能看到toc，因为大多数用户都会先通过移动端来接触文档，望大神能够满足这个需求。

The issue requests that the automatically generated table of contents be visible on mobile devices, but it names no files or tests. Start by locating the theme's TOC and mobile menu entry points, then verify the result at a mobile viewport; done means the document structure remains usable and the TOC is accessible on mobile.

Written by the indexing model from the issue text.
