Cannot get TOC to show on page type

[acyberrain]

Hello, I'm having issues getting showTableOfContents = "true" to work on type = "page". Works flawlessly on type = "post". Thoughts are much appreciated, thank you!

toc.html is default:

{{ if .Params.ShowTableOfContents }}
<aside class="post-toc">
    <nav id="toc">
        {{ .TableOfContents }}
    </nav>
</aside>
{{ end }}

single.html:

{{ define "main" }}
    {{ if eq .Type "post" }}
        {{- partial "post.html" . -}}
        {{- partial "toc.html" . -}}
    {{ end }}

    {{ if eq .Type "page" }}
        {{- partial "page.html" . -}}
        {{- partial "toc.html" . -}}
    {{ end }}
{{ end }}

hugo.toml:

[markup]
  [markup.tableOfContents]
    startLevel = 1
    ordered = false
    endLevel = 3

can you show your page document? I tried reproducing the error but it works fine

bludhaven.md

---
title: Blüdhaven
type: page
showTableOfContents: true
---

### History

Blüdhaven was a former whaling town, which was officially incorporated as a "Commonwealth" in 1912. The town had a generally poor socio-economic populace, owing in part to failed efforts to transform itself into a manufacturing and shipping center.

Hey @mansoorbarri -- here is page.html:

<div class="post container">

    <div class="post-header-section">
        <h1>{{ .Title }}</h1>
    </div>

    <div class="post-content">
        <p>
            {{ .Content }}
        </p>
    </div>

    {{ if .Site.Params.ShowBackToTopButton }}
    <svg id="btt-button" class="arrow-logo" xmlns="http://www.w3.org/2000/svg" height="1em" viewBox="0 0 384 512" onclick="topFunction()" title="Go to top">

    <script>
        let backToTopButton = document.getElementById("btt-button");

        window.onscroll = function() {
            scrollFunction()
        };

        function scrollFunction() {
            if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
                backToTopButton.style.display = "block";
            } else {
                backToTopButton.style.display = "none";
            }
        }

        function topFunction() {
            smoothScrollToTop();
        }

        function smoothScrollToTop() {
            const scrollToTop = () => {
                const c = document.documentElement.scrollTop || document.body.scrollTop;
                if (c > 0) {
                    window.requestAnimationFrame(scrollToTop);
                    window.scrollTo(0, c - c / 8);
                }
            };
            scrollToTop();
        }
    </script>   

</div>

can you share your md file which is using type: page like I shared bludhaven.md

[acyberrain]

@mansoorbarri -- Apologies, misread. Here is ..\content\cyber\_index.md:

+++
title = "Cyber"
type = "page"
ShowTableOfContents = "true"
+++
The Cyber section is split into multiple parts, which you can click on any of these links to navigate into:

Results in:

Whereas nested under this in ..\content\cyber\transition\index.md works fine:

+++
title = "Transitioning to Cyber"
type = "page"
showTableOfContents = "true"
+++

---

## Preamble
The world of cybersecurity

Resulting in:

[mansoorbarri]

are there any headings on the page titled "cyber"?

[acyberrain]

@mansoorbarri -- Yes. Full page excerpt:

+++
title = "Cyber"
type = "page"
ShowTableOfContents = "true"
+++
The Cyber section is split into multiple parts, which you can click on any of these links to navigate into:

# Career
Items.

## Sub-items
Test it out.

# Threat
Items again.

## More Sub-items
More testing it out.

[mansoorbarri]

seems fine here, can you share your repository please?

[acyberrain]

@mansoorbarri -- added you to acrwiki repo as a collaborator. Note that the headings I showed above are on my local-only, as this is a prod repo so I had to use a list instead. Thank you!

[mansoorbarri]

it seems to be working if you change your file name from _index.md to index.md. I am not entirely sure why this happens but my educated guess would be that _index.md pages are usually used to list articles & TOC wouldn't be needed for listing various articles.

More info: https://gohugo.io/content-management/organization/#index-pages-_indexmd

Screenshot of it working:

+++
title = "Cyber"
type = "page"
ShowTableOfContents = true
+++

## toc test

The Cyber section is split into multiple parts, which you can click on any of these links to navigate into:
1. [**Career Observations**](transition/){{< badge after="WIP" >}}
    - Last Updated: {{< badge before="🕐 11 Jan 2024" >}}
    - Transitioning into cyber can be daunting, in addition to growing within it or moving around specialties. Review this page for thoughts on different disciplines within the cyber field, what education you should consider (certifications/degree programs/courses), and my experience with going from public to private sector.
1. [**Threat Analysis**](analysis/){{< badge after="WIP" >}} 
    - Empty right now.
    - Blog-style organization in here with random threats I look at, around one to two posts every 3 months. A lot of phishing usually. No, this isn't derived from my corporate work, and does not represent my employer's analysis capabilities. This is entirely open source stuff that I just dabble in as I see it or as it's sent to me. My day job consumes the majority of my deep-dive thinking.p

@mansoorbarri -- Fascinating, I have been trying to figure this out for weeks and the underscore did not occur to me. Different filenames create this result, but then you can't use the files as your index. index.md works as intended when underscore is removed. Thank you!!
