Menu

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 index.md as menu.
Given you have this file structure

│   ├── docs
│   │   ├── page-one.md
│   │   └── page-two.md
│   └── posts
│       ├── post-one.md
│       └── post-two.md

headless = true

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

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

There are few configuration options you can add to your config.toml file.
You can also see yaml example here.

# (Optional) Set this to true if you use capital letters in file names
disablePathToLower = true

# (Optional) Set this to true to enable 'Last Modified by' date and git author
#  information on 'doc' type pages.
enableGitInfo = true

# (Optional) Theme is intended for documentation use, therefore it doesn't render taxonomy.
# You can remove related files with config below
disableKinds = ['taxonomy', 'taxonomyTerm']

[params]
# (Optional, default 6) Set how many table of contents levels to be showed on page.
# Use false to hide ToC, note that 0 will default to 6 (https://gohugo.io/functions/default/)

BookToC = 3
