Navigate to your hugo website root and run:

hugo server --theme book


File tree menu (default)

By default theme will render pages from content/docs section as menu in a tree structure.
You can set title and weight in front matter of pages to adjust order and titles in menu.

Leaf bundle menu

You can also use leaf bundle and content of it's as menu.

Given you have this file structure

├── content
│   ├── docs
│   │   ├──
│   │   └──
│   └── posts
│       ├──
│       └──

Create file content/docs/menu/ with content

headless: true

- [Book Example](/docs/)
  - [Page One](/docs/page-one)
  - [Page Two](/docs/page-two)
- [Blog](/posts)

And Enable it by settings BookMenuBundle: /docs/menu in Site configuration


Simple blog supported for section posts
