GitBook Plugin: Collapsible Menu

GitBook Plugin to change sidebar menu's to collapsible menu. For gitbook with many pages, navigating long menus can get irritating.

Usage

Update book.json file to include collapsible-menu plugin.

{
    "plugins": ["collapsible-menu"],
}

Troubleshooting

1. If you are not seeing all chapters expanded, then check if your book.json is valid. You can use this online tool - http://json.parser.online.fr/beta/
2. Check if you are using default gitbook theme. It is NOT recommended to modify gitbook themes directly
3. Clean your browser cache.
4. Check browser's javascript console for errors.

How this work?

It hooks into gitbook's page.change event. First it hides all pages, and then using .active css class show's its parent and grandparent nodes (chapters).

TODO

Testing with PDF book generation. I hope it won't break.
