Group sub-sections by param

support
1

I’m trying to group these Reports by the country listed alphabetically, and then display the two different reports in order by year.

Here’s the file structure:

Reports

  • argentina
    – 2020
    — index.md
    – 2016
    — index.md

  • brazil
    – 2020
    —index.md
    – 2016
    — index.md

I want the display to be, in alpha order:

Argentina
2020 report
2016 report

Brazil
2020 report
2016 report

I have tried:

{{ range (where .Site.Pages.ByTitle "Section" "reports") }}
        <h2 id="{{ .Params.Slug }}">{{ .Params.Name }}</h2>
         <h3><a href="{{.Permalink }}">{{ .Params.Title }}</a></h3>
          <p>{{ .Params.Intro }}<p>
 {{ end }}

But the results are:

Argentina
2016
Brazil
2016

Report 2020 (Argentina)
Report 2020 (Brazil)

I have also tried:

{{ range .Pages.GroupBy "Section" }}

… etc

and

{{ range where .Pages ".Params.country" .Params.country }}

and

   {{ range .Sections }}
    {{ .Title }}
    <ul>
        {{ range .Pages }}
        <li>
        <a href="{{ .Permalink }}">{{ .Title }}</a>
        </li>
        {{ end }}
    </ul>
  {{ end }}

Thanks for your help!
