Exclude a category from showing up in posts

I want to exclude a category from showing up in posts, mainly a category called myblog
I tried following: https://discourse.gohugo.io/t/exclude-a-category-from-list-html/25019
but it did not work.

here is my list.html code:

{{- define "main" }}

{{- if (and site.Params.profileMode.enabled .IsHome) }}
{{- partial "index_profile.html" . }}
{{- else }} {{/* if not profileMode */}}

{{- if not .IsHome | and .Title }}
<header class="page-header">
  {{- partial "breadcrumbs.html" . }}

  
  <h1>
    {{ .Title }}
    {{- if and (or (eq .Kind `term`) (eq .Kind `section`)) (.Param "ShowRssButtonInSectionTermList") }}
    <a href="index.xml" title="RSS" aria-label="RSS">
      <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2"
        stroke-linecap="round" stroke-linejoin="round" height="23">
        <path d="M4 11a9 9 0 0 1 9 9" />
        <path d="M4 4a16 16 0 0 1 16 16" />
        <circle cx="5" cy="19" r="1" />
      </svg>
    </a>
    {{- end }}
  </h1>
  
  {{- if .Description }}
  <div class="post-description">
    {{ .Description | markdownify }}
  </div>
  {{- end }}
</header>
{{- end }}




{{- if .Content }}
<div class="post-content">
  {{- if not (.Param "disableAnchoredHeadings") }}
  {{- partial "anchored_headings.html" .Content -}}
  {{- else }}{{ .Content }}{{ end }}
</div>
{{- end }}


{{- $pages := union .RegularPages .Sections }}

{{- if .IsHome }}
{{- $pages = where site.RegularPages "Type" "in" site.Params.mainSections }}
{{- $pages = where $pages "Params.hiddenInHomeList" "!=" "true"  }}
{{- end }}

{{- $paginator := .Paginate $pages }}

{{- if and .IsHome site.Params.homeInfoParams (eq $paginator.PageNumber 1) }}
{{- partial "home_info.html" . }}
{{- end }}



{{- $term := .Data.Term }}
{{- range $index, $page := $paginator.Pages }}

{{- $class := "post-entry" }}

{{- $user_preferred := or site.Params.disableSpecial1stPost site.Params.homeInfoParams }}
{{- if (and $.IsHome (eq $paginator.PageNumber 1) (eq $index 0) (not $user_preferred)) }}
{{- $class = "first-entry" }}
{{- else if $term }}
{{- $class = "post-entry tag-entry" }}
{{- end }}

<article class="{{ $class }}">
  {{- $isHidden := (site.Params.cover.hidden | default site.Params.cover.hiddenInList) }}
  {{- partial "cover.html" (dict "cxt" . "IsHome" true "isHidden" $isHidden) }}
  <header class="entry-header">
    <h2>
      {{- .Title }}
      {{- if .Draft }}<sup><span class="entry-isdraft">&nbsp;&nbsp;[draft]</span></sup>{{- end }}
    </h2>
  </header>
  {{- if (ne (.Param "hideSummary") true) }}
  <div class="entry-content">
    <p>{{ .Summary | plainify | htmlUnescape }}{{ if .Truncated }}...{{ end }}</p>
  </div>
  {{- end }}
  {{- if not (.Param "hideMeta") }}
  <footer class="entry-footer">
    {{- partial "post_meta.html" . -}}
  </footer>
  {{- end }}
  <a class="entry-link" aria-label="post link to {{ .Title | plainify }}" href="{{ .Permalink }}"></a>
</article>
{{- end }}

{{- if gt $paginator.TotalPages 1 }}
<footer class="page-footer">
  <nav class="pagination">
    {{- if $paginator.HasPrev }}
    <a class="prev" href="{{ $paginator.Prev.URL | absURL }}">
      «&nbsp;{{ i18n "prev_page" }}&nbsp;
      {{- if (.Param "ShowPageNums") }}
      {{- sub $paginator.PageNumber 1 }}/{{ $paginator.TotalPages }}
      {{- end }}
    </a>
    {{- end }}
    {{- if $paginator.HasNext }}
    <a class="next" href="{{ $paginator.Next.URL | absURL }}">
      {{- i18n "next_page" }}&nbsp;
      {{- if (.Param "ShowPageNums") }}
      {{- add 1 $paginator.PageNumber }}/{{ $paginator.TotalPages }}
      {{- end }}&nbsp;»
    </a>
    {{- end }}
  </nav>
</footer>
{{- end }}

{{- end }}{{/* end profileMode */}}

{{- end }}{{- /* end main */ -}}

Would be helpful to post the part of the code that is the problem, the logic of the whole thing is a lot to go through.
Do you mean category or section?

{{- $pages := union .RegularPages .Sections }}
{{- if .IsHome }}
{{- $pages = where site.RegularPages "Type" "in" site.Params.mainSections }}
{{- $pages = where $pages "Params.hiddenInHomeList" "!=" "true" }}
{{- end }}

Is it this part?
So you want to only to exclude category/section on the homepage?
Creating $pages for NOT home could be done in an {{ else }}. It would save creating it when it doesn’t use it.
You are testing for the string “true” I think that might work anyway but you are probably testing for a Boolean true.
