Usage

plugins:
  - nav-numbering:
      nav_depth: 4
      heading_depth: 5
      number_h1: true
      number_nav: true
      number_headings: true
      preserve_anchor_ids: false
      separator: "."
      exclude:
        - index.md

markdown_extensions:
  - attr_list  # Required when preserve_anchor_ids is true

Options

• enabled (bool, default: true)
• nav_depth (int, default: 0) — 0 means unlimited
• heading_depth (int, default: 0) — 0 means unlimited
• number_nav (bool, default: true)
• number_headings (bool, default: true)
• number_h1 (bool, default: true)
• preserve_anchor_ids (bool, default: false) — Preserve original heading anchor IDs without number prefixes (requires attr_list)
• separator (str, default: ".")
• exclude (list, default: [])

preserve_anchor_ids

By default, MkDocs generates heading IDs from the final heading text. Since this plugin prepends numbering, your anchors can end up including the numbers.

Enable preserve_anchor_ids: true to add explicit {#...} IDs based on the original (un-numbered) heading text. Duplicate headings are automatically suffixed with -1, -2, etc.

plugins:
  - nav-numbering:
      preserve_anchor_ids: true
