sidebar	Sidebar

To generate a sidebar to your Docusaurus site, you need to define a file that exports a JS module and pass that into the @docusaurus/plugin-docs plugin directly or via @docusaurus/preset-classic. If you are using the classic preset, you can find the sidebars.js under the root directory already created for you, so you may edit it directly for customization.

website # root directory of your site
├── docs
│   └── greeting.md
├── docusaurus.config.js
├── sidebars.js
.

To add a doc to the sidebar, add the id specified in the frontmatter of the doc into its category.

module.exports = {
  docs: {
+   "Getting started": ["greeting"],
    "Docusaurus": ["doc1"],
    "First Category": ["doc2"],
    "Second Category": ["doc3"],
  }
};

The docs key in the exported object is just the name of that particular sidebar hierarchy, and can be renamed to something else. You can have multiple sidebars for different Markdown files by adding more top-level keys to the exported object.

Subcategories

To include subcategories in docs sidebar, use an object of the following shape

{
  type: 'category',
  label: string, // sidebar label
  items: string[], // strings of doc ids
}

in place of a string of id. As an example, here's how we created the subcategory for "Docs" under "Guides" in this site:

// sidebars.js
module.exports = {
  docs: {
    Guides: [
      'creating-pages',
      {
        type: 'category',
        label: 'Docs',
        items: ['markdown-features', 'sidebar'],
      },
    ],
  },
};

Note: Only one layer of nestedness is allowed.

Note: We're implementing a new sidebar!
