Build options are stored in a reserved front matter object named _build with these defaults:

{{< code-toggle file=content/example/index.md fm=true >}} [_build] list = 'always' publishResources = true render = 'always' {{< /code-toggle >}}

list

When to include the page within page collections. Specify one of:

• always

  Include the page in all page collections. For example, site.RegularPages, .Pages, etc. This is the default value.

• local

  Include the page in local page collections. For example, .RegularPages, .Pages, etc. Use this option to create fully navigable but headless content sections.

• never

  Do not include the page in any page collection.

publishResources

Applicable to page bundles, determines whether to publish the associated page resources. Specify one of:

• true

  Always publish resources. This is the default value.

• false

  Only publish a resource when invoking its Permalink, RelPermalink, or Publish method within a template.

render

When to render the page. Specify one of:

• always

  Always render the page to disk. This is the default value.

• link

  Do not render the page to disk, but include it in all page collections.

• never

  Never render the page to disk, and exclude it from all page collections.

{{% note %}} Any page, regardless of its build options, will always be available by using the .Page.GetPage or .Site.GetPage method.

{{% /note %}}

Example -- headless page

Create a unpublished page whose content and resources can be included in other pages.

content/
├── headless/
│   ├── a.jpg
│   ├── b.jpg
│   └── index.md  <-- leaf bundle
└── _index.md     <-- home page

Set the build options in front matter:

{{< code-toggle file=content/headless/index.md fm=true >}} title = 'Headless page' [_build] list = 'never' publishResources = false render = 'never' {{< /code-toggle >}}

To include the content and images on the home page:

{{< code file=layouts/_default/home.html >}} {{ with .Site.GetPage "/headless" }} {{ .Content }} {{ range .Resources.ByType "image" }} {{ end }} {{ end }} {{< /code >}}

The published site will have this structure:

public/
├── headless/
│   ├── a.jpg
│   └── b.jpg
└── index.html

In the example above, note that:

1. Hugo did not publish an HTML file for the page.
2. Despite setting publishResources to false in front matter, Hugo published the page resources because we invoked the RelPermalink method on each resource. This is the expected behavior.

Example -- headless section

Create a unpublished section whose content and resources can be included in other pages.

content/
├── headless/
│   ├── note-1/
│   │   ├── a.jpg
│   │   ├── b.jpg
│   │   └── index.md  <-- leaf bundle
│   ├── note-2/
│   │   ├── c.jpg
│   │   ├── d.jpg
│   │   └── index.md  <-- leaf bundle
│   └── _index.md     <-- branch bundle
└── _index.md         <-- home page

Set the build options in front matter, using the cascade keyword to "cascade" the values down to descendant pages.

{{< code-toggle file=content/headless/_index.md fm=true >}} title = 'Headless section' cascade [cascade._build] list = 'local' publishResources = false render = 'never' {{< /code-toggle >}}

In the front matter above, note that we have set list to local to include the descendant pages in local page collections.

To include the content and images on the home page:

{{< code file=layouts/_default/home.html >}} {{ with .Site.GetPage "/headless" }} {{ range .Pages }} {{ .Content }} {{ range .Resources.ByType "image" }} {{ end }} {{ end }} {{ end }} {{< /code >}}

The published site will have this structure:

public/
├── headless/
│   ├── note-1/
│   │   ├── a.jpg
│   │   └── b.jpg
│   └── note-2/
│       ├── c.jpg
│       └── d.jpg
└── index.html

In the example above, note that:

1. Hugo did not publish an HTML file for the page.
2. Despite setting publishResources to false in front matter, Hugo correctly published the page resources because we invoked the RelPermalink method on each resource. This is the expected behavior.

Example -- list without publishing

Publish a section page without publishing the descendant pages. For example, to create a glossary:

content/
├── glossary/
│   ├── _index.md
│   ├── bar.md
│   ├── baz.md
│   └── foo.md
└── _index.md

Set the build options in front matter, using the cascade keyword to "cascade" the values down to descendant pages.

{{< code-toggle file=content/glossary/_index.md fm=true >}} title = 'Glossary' [_build] render = 'always' cascade [cascade._build] list = 'local' publishResources = false render = 'never' {{< /code-toggle >}}

To render the glossary:

{{< code file=layouts/glossary/list.html >}}

{{ range .Pages }}

{{ .Title }}

{{ .Content }}

{{ end }}

{{< /code >}}

The published site will have this structure:

public/
├── glossary/
│   └── index.html
└── index.html

Example -- publish without listing

Publish a section's descendant pages without publishing the section page itself.

content/
├── books/
│   ├── _index.md
│   ├── book-1.md
│   └── book-2.md
└── _index.md

Set the build options in front matter:

{{< code-toggle file=content/books/_index.md >}} title = 'Books' [_build] render = 'never' list = 'never' {{< /code-toggle >}}

The published site will have this structure:

public/
├── books/
│   ├── book-1/
│   │   └── index.html
│   └── book-2/
│       └── index.html
└── index.html

Example -- conditionally hide section

Consider this example. A documentation site has a team of contributors with access to 20 custom shortcodes. Each shortcode takes several arguments, and requires documentation for the contributors to reference when using them.

Instead of external documentation for the shortcodes, include an "internal" section that is hidden when building the production site.

content/
├── internal/
│   ├── shortcodes/
│   │   ├── _index.md
│   │   ├── shortcode-1.md
│   │   └── shortcode-2.md
│   └── _index.md
├── reference/
│   ├── _index.md
│   ├── reference-1.md
│   └── reference-2.md
├── tutorials/
│   ├── _index.md
│   ├── tutorial-1.md
│   └── tutorial-2.md
└── _index.md

Set the build options in front matter, using the cascade keyword to "cascade" the values down to descendant pages, and use the target keyword to target the production environment.

{{< code-toggle file=content/internal/_index.md >}} title = 'Internal' cascade [cascade._build] render = 'never' list = 'never' [cascade._target] environment = 'production' {{< /code-toggle >}}

The production site will have this structure:

public/
├── reference/
│   ├── reference-1/
│   │   └── index.html
│   ├── reference-2/
│   │   └── index.html
│   └── index.html
├── tutorials/
│   ├── tutorial-1/
│   │   └── index.html
│   ├── tutorial-2/
│   │   └── index.html
│   └── index.html
└── index.html
