Hugo makes no assumptions about how your rendered HTML will be structured. Instead, it provides all of the functions you will need to be able to build your menu however you want.

The following is an example:

{{< code file="layouts/partials/sidebar.html" download="sidebar.html" >}}

{{ $currentPage := . }} {{ range .Site.Menus.main }} {{ if .HasChildren }}
• {{ .Pre }} {{ .Name }}
{{ range .Children }}
• {{ .Name }}
{{ end }}
{{ else }}
• {{ .Pre }} {{ .Name }}
{{ end }} {{ end }}
• Hardcoded Link 1
• Hardcoded Link 2

{{< /code >}}

{{% note "absLangURL and relLangURL" %}} Use the absLangURL or relLangURL functions if your theme makes use of the multilingual feature. In contrast to absURL and relURL, these two functions add the correct language prefix to the url. {{% /note %}}

Section Menu for Lazy Bloggers

To enable this menu, configure sectionPagesMenu in your site config:

sectionPagesMenu = "main"

The menu name can be anything, but take a note of what it is.

This will create a menu with all the sections as menu items and all the sections' pages as "shadow-members". The shadow implies that the pages isn't represented by a menu-item themselves, but this enables you to create a top-level menu like this:

<nav class="sidebar-nav">
    {{ $currentPage := . }}
    {{ range .Site.Menus.main }}
    <a class="sidebar-nav-item{{if or ($currentPage.IsMenuCurrent "main" .) ($currentPage.HasMenuCurrent "main" .) }} active{{end}}" href="{{ .URL }}" title="{{ .Title }}">{{ .Name }}</a>
    {{ end }}
</nav>

In the above, the menu item is marked as active if on the current section's list page or on a page in that section.

Site Config menus

The above is all that's needed. But if you want custom menu items, e.g. changing weight, name, or link title attribute, you can define them manually in the site config file:

{{< code-toggle file="config" >}} menu.main name = "This is the blog section" title = "blog section" weight = -110 identifier = "blog" url = "/blog/" {{</ code-toggle >}}

{{% note %}} The identifier must match the section name. {{% /note %}}

Menu Entries from the Page's front matter

It's also possible to create menu entries from the page (i.e. the .md-file).

Here is a yaml example:

---
title: Menu Templates
linktitle: Menu Templates
menu:
  docs:
    title: "how to use menus in templates"
    parent: "templates"
    weight: 130
---
...

{{% note %}} You can define more than one menu. It also doesn't have to be a complex value, menu can also be a string, an array of strings, or an array of complex values like in the example above. {{% /note %}}

Using .Page in Menus

If you use the front matter method of defining menu entries, you'll get access to the .Page variable. This allows to use every variable that's reachable from the page variable.

This variable is only set when the menu entry is defined in the page's front matter. Menu entries from the site config don't know anything about .Page.

That's why you have to use the go template's with keyword or something similar in your templating language.

Here's an example:

<nav class="sidebar-nav">
  {{ range .Site.Menus.main }}
    <a href="{{ .URL }}" title="{{ .Title }}">
      {{- .Name -}}
      {{- with .Page -}}
        <span class="date">
        {{- dateFormat " (2006-01-02)" .Date -}}
        </span>
      {{- end -}}
    </a>
  {{ end }}
</nav>

Using .Params in Menus

User-defined content on menu items are accessible via .Params.

Here's an example:

<nav class="sidebar-nav">
  {{ range .Site.Menus.main }}
    <a href="{{ .URL }}" title="{{ .Title }}" class="{{ with .Params.class }}{{ . }}{{ end }}">
      {{- .Name -}}
    </a>
  {{ end }}
</nav>

{{% note %}} With Menu-level .Params they can easily exist on one menu item but not another. It's recommended to access them gracefully using the with function. {{% /note %}}
