Show Articles with certain tag but exclude imediate children

Hello,

I’m working on a section layout template where the sub articles of this page are linked. In addition I would like to also see those articles that are not direct children, but have a specific tag set in the front matter.

My Content Structure looks like this :

content
– Other
----- Page3
------- Page3.md (tags: tag Title:‘Test’)
– Section
---- A
------ index.md (tags: tag Title:‘Section A’)
---- B
------ index.md (tags: tag Title:‘Section B’)
----_index.md (filter: tag)
– _index.md

My partial script for the section layout is in the spoiler below.

Partial 
{{ if .page.Pages }}
<div>
    *{{ template "section-tree-nav" .page }}*
    {{ if isset .page.Params "filter" }}
        {{ template "section-tree-tags" .page }}
    {{ end }}
</div>
{{ end }}

{{ define "section-tree-nav" }}
{{ $visible_child_pages := where .Pages.ByTitle "Params.include_in_toc" "!=" "false" }}
{{ if $visible_child_pages }}
  <ul>
    {{ range $visible_child_pages }}
      <li>
          <a href="{{ .RelPermalink }}">{{ .Title }}</a>
            {{ template "section-tree-nav" . }}
      </li>
    {{ end }}
  </ul>
{{ end }}
{{ end }}

{{ define "section-tree-tags" }}
    {{ $allpages := where .Site.Pages.ByTitle "Params.include_in_toc" "!=" "false" }}   
    {{ $visible_child_pages := where .Pages.ByTitle "Params.include_in_toc" "!=" "false" }}
    {{ $filter := (slice .Params.filter) }}
    {{/* General Problem : the pages that are already in other categories, would show up here as well*/}}
    <ul>
    <li>
          <a>Filtered Tag '{{(index $filter 0)}}'</a>
    </li>
    {{ $filteredpages := where $allpages "Params.tags" "intersect" $filter}}
    {{ range $filteredpages }}
    <ul>
         <li>
          <a href="{{ .RelPermalink }}">{{ .Title }}</a>
            {{ template "section-tree-nav" . }}
        </li>
    </ul>
    {{ end }}
    </ul>

{{ end }}

My question regarding this is now : How can I filter out the Pages that area already displayed, because they are direct children of the section page ?

The way this script is now, I see Test,Section A and Section B below the FilterTag element if I look a the section page called Section, but I only want to see the Link for Test, the element that is not a direct sub element.

Looking forward to your Suggestions

Found a Solution on my own. I wasn’t aware of the complement function and did not pass through the article while browsing the documentation.
