Custom variables in Menus in multilingual site

[fjk]

I am trying to add custom variables to menu entries. My site is multilingual and I added the navigation items to a translated menu inside config/_default/languages.toml

Example:

[en]
  weight = 1
  languageName = 'English'
  contentDir = "content/en"
  [[en.menu.main]]
    name = 'About us'
    pageRef = '/about'
    weight = 10
    action = 'ContactAction'
  [[en.menu.main]]
    name = 'Career'
    pageRef = '/career'
    weight = 20
    action = 'ReadJobPostingAction'

I was reading through this support question to find out how to attach custom action attributes to a menu.

While stated otherwise, it turns out, this actually is supported:

{{- range $a := .Site.Params.menus.main }}
    {{ printf "%#v" $a.action }}
{{- end }}

which prints

"ContactAction"
"ReadJobPostingAction"

The topic you refer to is wildly inaccurate. These statements are utterly false:

Currently there is no support for custom menu variables.

So the bottom line is: no custom properties in menu definitions.

The params menu entry property is described here:
https://gohugo.io/content-management/menus/#properties-front-matter

Examples of menu entries with a params table:

The .Params menu entry variable is described here:

An example of rendering a menu entry parameter:

I have no idea why you placed menu items under the site configuration’s params table, but this is the wrong way to do it.

Thanks for making things clear.

Well, I did not. They only reside inside config/default/languages.toml as shown above. Anyway, thanks to your links, I changed it to the following, which works:

[en]
  weight = 1
  languageName = 'English'
  contentDir = "content/en"
  [[en.menu.main]]
    name = 'About us'
    pageRef = '/about'
    weight = 10
    [en.menu.main.params]
      action = 'ContactAction'
  [[en.menu.main]]
    name = 'Career'
    pageRef = '/career'
    weight = 20
    [en.menu.main.params]
      action = 'ReadJobPostingAction'

Now the following is what I can use:

{{- range $i, $e := site.Menus.main }}{{ if $i }}, {{- end }}
    {{ with .Params -}}{{ .action }}{{ end -}}
    {{ $e.Name }}
    {{ $e.PageRef | absURL }}
{{- end }}
