MainSections

SITE.MainSections

[]string

Site configuration:

params:
  mainSections:
  - books
  - films

[params]
  mainSections = ['books', 'films']

{
   "params": {
      "mainSections": [
         "books",
         "films"
      ]
   }
}

Template:

{{ .Site.MainSections }} → [books films]

If params.mainSections is not defined in the site configuration, this method returns a slice with one element—the top level section with the most pages.

With this content structure, the “films” section has the most pages:

content/
├── books/
│   ├── book-1.md
│   └── book-2.md
├── films/
│   ├── film-1.md
│   ├── film-2.md
│   └── film-3.md
└── _index.md

Template:

{{ .Site.MainSections }} → [films]

When creating a theme, instead of hardcoding section names when listing the most relevant pages on the front page, instruct site authors to set params.mainSections in their site configuration.

Then your home template can do something like this:

{{ range where .Site.RegularPages "Section" "in" .Site.MainSections }}
  <h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
{{ end }}
