This GitBook plugin adds an inline table of contents (TOC) to each page based on configurable selectors. Inline TOC can be enabled or disabled by default or on individual pages. TOC is placed on the right side and moves to top for smaller devices automatically.

Inline TOC stays at the top of the page when scrolling using a sticky effect. Current position is highlighted by a scrollspy effect.

Plugin uses gumshoe and anchorjs to implement functionality.

1. In you gitbook's book.json file, add intopic-toc to plugins list.
2. In pluginsConfig, configure the plugin so it does fit your needs. A custom setup is not mandatory.

Sample book.json file for gitbook version 2.0.0+

{
  "plugins": [
    "intopic-toc"
  ]
}

Sample book.json file for gitbook version 2.0.0+ and custom heading

{
  "plugins": [
    "intopic-toc"
  ],
  "pluginsConfig": {
    "intopic-toc": {
      "label": "Navigation"
    }
  }
}

Sample book.json file for gitbook version 2.0.0+ and multilingual headings

{
  "plugins": [
    "intopic-toc"
  ],
  "pluginsConfig": {
    "intopic-toc": {
      "label": {
        "de": "In diesem Artikel",
        "en": "In this article"
      }
    }
  }
}

Note: Above snippets can be used as complete book.json file, if one of these matches your requirements and your book doesn't have one yet.

1. Run gitbook install. It will automatically install intopic-toc gitbook plugin for your book. This is needed only once.
2. Build your book (gitbook build) or serve (gitbook serve) as usual.

For basic usage, the only thing you have to do is install the plugin. For advanced scenarios see following configuration sample.

{
  "plugins": [
    "intopic-toc"
  ],
  "pluginsConfig": {
    "intopic-toc": {
      "selector": ".markdown-section h2",
      "visible": true,
      "label": {
        "de": "In diesem Artikel",
        "en": "In this article"
      },
    }
  }
}

If visible parameter set to true and you want to hide the TOC on a single page, add the front matter item isTocVisible: false to the top of the Markdown file like this:

---
isTocVisible: false
---
# My awesome documentation

Lorem ipsum dolor sit amet, consetetur sadipscing elitr, ...

The specific front matter isTocVisible overrides the visible parameter from global configuration.

If inline TOC does not look as expected, check if your book.json is valid according to this documentation.
