Here's the sidebar at V1: https://github.com/wu-clan/httpfpt_docs/blob/5ff0f1b19eab155e575431b73f5eed6faad26ebd/docs/.vuepress/config.js#L58

It's all working fine!

Try adding .html suffix to your config.

For now only if you set the link to equal the route path, then the default theme will automatically add sub headers for you:
