#765 & #766 were things i ran into trying to figure out the subject of this ticket.

is there any way to set a toc start level on a per page (or directory) basis? i have a few pages where i'd like a startlevel of 1, but only a few. for the rest i prefer startlevel 2.

it seems that the only place where markup's depth is accepted is in the main hugo.toml/yaml

[markup]
  [markup.goldmark.renderer]
    unsafe = true
  [markup.tableofcontents]
    startlevel = 1
    endlevel = 4

i tried every variation of frontmatter i could think of in both toml & yaml syntax but only the startlevel in hugo.toml has effect. (booktoc true/false does work per page)

i know that i have a lot of double parameters, this is just to show what/where i tried in frontmatter:

---
date: '2025-09-04T16:54:32+02:00'
title: 'first steps in the sas world'
description: 'first steps in the sas world'
weight: 20
BookToc: true
markup:
  tableOfContents:
    startLevel: 3
params:
  eid: here
  BookToc: true
  markup:
    tableOfContents:
      startLevel: 3
---

none of it had any effect. if it's indeed defined only in the main hugo file then feel free to close this issue.

thx in advance
