Overview
After defining menu entries, use menu variables and methods to render a menu.
Three factors determine how to render a menu:
- The method used to define the menu entries: automatic, in front matter, or in site configuration
- The menu structure: flat or nested
- The method used to localize the menu entries: site configuration or translation tables
The example below handles every combination.
Example
This partial template recursively "walks" a menu structure, rendering a localized, accessible nested list.
{{< code file=layouts/partials/menu.html copy=true >}} {{- $page := .page }} {{- $menuID := .menuID }}
{{- with index site.Menus $menuID }}
-
{{- partial "inline/menu/walk.html" (dict "page" $page "menuEntries" .) }}
{{- define "partials/inline/menu/walk.html" }} {{- $page := .page }} {{- range .menuEntries }} {{- $attrs := dict "href" .URL }} {{- if $page.IsMenuCurrent .Menu . }} {{- $attrs = merge $attrs (dict "class" "active" "aria-current" "page") }} {{- else if $page.HasMenuCurrent .Menu .}} {{- $attrs = merge $attrs (dict "class" "ancestor" "aria-current" "true") }} {{- end }} {{- $name := .Name }} {{- with .Identifier }} {{- with T . }} {{- $name = . }} {{- end }} {{- end }}
-
{{- partial "inline/menu/walk.html" (dict "page" $page "menuEntries" .) }}
Call the partial above, passing a menu ID and the current page in context.
{{< code file=layouts/_default/single.html >}} {{ partial "menu.html" (dict "menuID" "main" "page" .) }} {{ partial "menu.html" (dict "menuID" "footer" "page" .) }} {{< /code >}}
Page references
Regardless of how you define menu entries, an entry associated with a page has access to page variables and methods.
This simplistic example renders a page parameter named version
next to each entry's name
. Code defensively using with
or if
to handle entries where (a) the entry points to an external resource, or (b) the version
parameter is not defined.
{{< code file=layouts/_default/single.html >}} {{- range site.Menus.main }} {{ .Name }} {{- with .Page }} {{- with .Params.version -}} ({{ . }}) {{- end }} {{- end }} {{- end }} {{< /code >}}
Menu entry parameters
When you define menu entries in site configuration or in front matter, you can include a params
key as shown in these examples:
This simplistic example renders a class
attribute for each anchor element. Code defensively using with
or if
to handle entries where params.class
is not defined.
{{< code file=layouts/partials/menu.html >}} {{- range site.Menus.main }} <a {{ with .Params.class -}} class="{{ . }}" {{ end -}} href="{{ .URL }}"> {{ .Name }} {{- end }} {{< /code >}}
Localize
Hugo provides two methods to localize your menu entries. See multilingual.
