Navigation

Your sidebar and top bar are defined entirely in docs.json. The navigation hierarchy has three levels: tabs for top-level sections, groups for collapsible folders, and pages for individual entries. Anchors add external links that appear on every page.

Structure Overview

docs.json

{
  "navigation": {
    "tabs": [
      {
        "tab": "Documentation",
        "icon": "book-open",
        "groups": [
          {
            "group": "Getting Started",
            "pages": ["introduction", "quickstart"]
          }
        ]
      }
    ]
  }
}

Concepts

Tabs

Top-level navigation sections. Control their position with the tabsPosition setting:

Value	Position
`"top"`	In the header tab bar
`"left"`	At the top of the sidebar

The default position depends on your theme:

Theme	Default
jam	`"left"`
nebula	`"left"`
pulsar	`"top"`

{
  "tabsPosition": "left",
  "navigation": {
    "tabs": [
      { "tab": "Guides", "icon": "book", "groups": [...] },
      { "tab": "API", "icon": "code", "groups": [...] }
    ]
  }
}

Sidebar icons render in the Font Awesome Solid variant by default. Override any icon's weight with a style prefix (light/book) or the icon object form.

External Links (Anchors)

Add external links that appear at the top of the sidebar on all pages:

{
  "anchors": [
    { "name": "Blog", "href": "https://blog.example.com", "icon": "newspaper" },
    { "name": "Status", "href": "https://status.example.com", "icon": "signal" }
  ]
}

Field	Type	Required	Description
`name`	string	Yes	Display text for the link
`href`	string	Yes	URL (opens in new tab)
`icon`	string	No	Font Awesome icon name

Groups

A group is a labeled set of sidebar entries inside a tab. Groups add a second level of hierarchy to your sidebar and let you hide deeper sections behind accordion-style folders.

{
  "group": "Authentication",
  "pages": ["auth/overview", "auth/tokens"]
}

Section and accordion behavior

Top-level groups are permanent sections: the title and its pages are always visible, and clicking the title jumps to the group's first page. Nested named groups are collapsible accordions. A nested group starts closed unless it contains the current page or sets expanded: true. On initial load and route changes, the current page's full ancestor chain opens automatically so the active link is revealed; visitors may still collapse the active nested group manually.

Group type	Default behavior
Top-level group	Always open, no chevron. Clicking the title navigates to the group's first page.
Nested named group	Collapsed until active, manually opened, or configured with `expanded: true`. Clicking a closed group opens it and clicking an open group closes it; navigation only happens when you click a page.
Unnamed container	Always renders its pages because it has no label or toggle control.

Use top-level groups for the major sections of your sidebar and nested groups to keep longer sections scannable. Expansion state persists during in-app navigation and resets on a full page refresh.

Sidebar with the 'Privacy & Access' group collapsed: chevron points right, child pages hidden — A nested group in its collapsed state. The chevron points right and the child pages are hidden.

Sidebar with the 'Privacy & Access' group expanded: chevron rotated down, three child pages visible below — The same group after navigating to one of its child pages. The chevron rotates and the child pages appear below.

Group fields

Field	Type	Required	Description
`group`	string	Yes	Display label shown in the sidebar.
`pages`	array	Yes	List of page paths and/or nested group objects (see Nested Groups for the nested shape).
`icon`	string	No	Font Awesome icon name displayed beside the group label.
`tag`	string	No	Small badge next to the label (e.g., `"New"`, `"Beta"`).
`root`	string	No	Page path the group links to when the label is clicked (instead of jumping to the first child page).
`hidden`	boolean	No	Hide the group from the sidebar by default. The pages remain reachable by direct link.
`public`	boolean	No	Mark the group as publicly accessible. Defaults to the parent tab's setting.
`expanded`	boolean	No	Open a nested named group by default on first page load. Top-level groups are always open, so the flag has no visible effect there. The current page's ancestor groups open automatically on initial load and route changes.

Pages

Individual documentation pages, referenced by their file path (without .mdx):

"pages": ["introduction", "guides/quickstart", "api/endpoints"]

By default, the sidebar title is generated from the file name: dashes become spaces and each word is capitalized. For example, "api/getting-started" displays as "Getting Started".

To set a custom sidebar title, use an object instead of a string:

"pages": [
  "guides/quickstart",
  { "page": "deploy/aws", "title": "AWS Route 53 & CloudFront" },
  { "page": "content/seo", "title": "SEO" },
  { "page": "api/users", "title": "List Users", "method": "GET" }
]

This is useful for acronyms, proper nouns, and API endpoint badges.

Field	Type	Required	Description
`page`	string	Yes	File path without `.mdx`
`title`	string	No	Custom sidebar title
`icon`	string	No	Font Awesome icon name
`tag`	string	No	Small badge next to the title (e.g., "New", "Beta")
`method`	string	No	HTTP method badge: GET, POST, PUT, PATCH, or DELETE

Multiple Tabs

Create separate sections for different audiences:

{
  "navigation": {
    "tabs": [
      {
        "tab": "Guides",
        "icon": "book",
        "groups": [
          { "group": "Getting Started", "pages": ["intro", "quickstart"] }
        ]
      },
      {
        "tab": "API Reference",
        "icon": "code",
        "groups": [{ "group": "Endpoints", "pages": ["api/auth", "api/users"] }]
      }
    ]
  }
}

External Tab Links

Link to external documentation or resources directly from tabs:

{
  "navigation": {
    "tabs": [
      { "tab": "Docs", "icon": "book", "groups": [...] },
      { "tab": "GitHub", "icon": "github", "href": "https://github.com/example/repo" }
    ]
  }
}

External tabs open in a new browser tab.

Nested Groups

Organize complex documentation with nested structures:

{
  "group": "SDKs",
  "pages": [
    "sdks/overview",
    {
      "group": "JavaScript",
      "pages": ["sdks/js/install", "sdks/js/usage"]
    },
    {
      "group": "Python",
      "pages": ["sdks/python/install", "sdks/python/usage"]
    }
  ]
}
