Body Foot Util Area

CreatedApr 27, 2026Takeshi Takatsudo

The right-aligned strip below every doc page that hosts the Document History trigger and the "View source on GitHub" link.

Every doc page renders a small utility strip between the article body and the footer. The strip hosts the Document History trigger and a “View source on GitHub” link, both configured through one settings block: bodyFootUtilArea.

📝 Note

The History button used to render as a floating element. It now lives inside this area — see Document History for the feature itself.

Default configuration

export const settings = {
  // ...
  githubUrl: "https://github.com/zudolab/zudo-doc",
  docHistory: true,
  bodyFootUtilArea: {
    docHistory: true,
    viewSourceLink: true,
  },
};

Both entries default to true. Set the whole block to false to hide the strip entirely:

bodyFootUtilArea: false,

Fields

Field	Type	Description
`docHistory`	boolean	Show the Document History trigger inside the strip. Requires top-level `docHistory: true`.
`viewSourceLink`	boolean	Show the “View source on GitHub” link. Requires top-level `githubUrl` to be set.

The strip is only rendered if at least one item is visible. If docHistory: false AND viewSourceLink: false (or both dependencies are off), the strip disappears and the page footer flows directly under the article.

View source on GitHub

When viewSourceLink is enabled and githubUrl is set, each page shows a link to its source .mdx file on GitHub. The URL is built as:

${githubUrl}/blob/HEAD/${contentDir}/${entryId}

where contentDir is the page’s content directory (e.g. src/content/docs for English, src/content/docs-ja for Japanese, or the docsDir of the active version) and entryId is the page’s file path within that directory.

Page	Resolved URL
`/docs/guides/header-navigation`	`https://github.com/…/blob/HEAD/src/content/docs/guides/header-navigation.mdx`
`/ja/docs/guides/header-navigation`	`https://github.com/…/blob/HEAD/src/content/docs-ja/guides/header-navigation.mdx`

ℹ️ Info

The URL pins to HEAD — not a specific branch. GitHub resolves HEAD to your repo’s default branch, so the link always points at the latest version without hard-coding a branch name.

Japanese fallback pages

If a Japanese page falls back to English content, the link still points to the actual file that rendered — the English src/content/docs/ file in that case.

Hiding a single item

Turn off only the pieces you don’t want:

// Keep history, hide source link
bodyFootUtilArea: {
  docHistory: true,
  viewSourceLink: false,
},

// Hide history, keep source link
bodyFootUtilArea: {
  docHistory: false,
  viewSourceLink: true,
},

Toggling docHistory here is independent from the top-level docHistory flag: the top-level flag controls the overall feature (including build-time generation); the bodyFootUtilArea.docHistory flag just controls whether the trigger button appears inside the strip.
