Creating a table of contents with Qgoda is very easy. And every aspect of it can be styled to your needs.


Location of the Table of Contents

First you have to mark, where in your document you want the table of contents to appear:

This is a long article with a lot of sections.

Use the above table of contents to find your way.

The custom tag <qgoda-toc/> is expanded into a table of contents like the one you can see at the top of this page, when rendering the document.

You can place the the tag inside of the markdown documents you write or inside the view templates. You can even place it multiple times.

Marking the Content Range

The table of contents is generated over only a part of the document. This will normally be the content area, the part of the document that you write in markdown. Search for [% asset.content %] in the files _views directory:

<div class="container">
  [% asset.content %]

Surround it with the custom tag <qgoda-content>:

<div class="container">
  [% asset.content %]

Qgoda will now create a document structure from all <h2> to <h6> elements found between <qgoda-content> and </qgoda-content> and render it as a table of contents, wherever you put the tag <qgoda-toc>.

Template für das Inhaltsverzeichnis

When you render a page with a table of contents for the first time you may notice the following log output:

[warning] writing default template '_views/components/toc/level.html'
[warning] writing default template '_views/components/toc.html'

You can see that the template files _views/components/toc/level.html and _views/components/toc.html have been automatically generated for you. They are meant as a starting point and hint. You normally have to at least add some general styling in your CSS files for the classes uses. The table of contents that you can see at the top of this page was styled with the following CSS:

.toc {
    border: 1px dotted #818a91;
    background-color: #f7f7f9;
    margin-bottom: 1rem;
    padding: 0.5rem;
    padding-bottom: 0rem;

.toc ul {
    list-style-type: none;

.toc .toc-title {
    font-weight: bold;
    font-size: 110%;
    padding-bottom: 0.5rem;

ul.toclevel-1 {
   padding-left: 0;

Details und Konfiguration

The table of contents generation is implemented as a HTMLFilter plug-in. That means it is executed at the very end of the rendering process.

Internal Logic

The plug-in finds all <h2> to <h6> elements and generates a hierarchy from the tags found. It is quite strict. For example, an <h4> tag after an <h3> tag is ignored because the hierarchy level <h3> is missing.

It collects the document structure and passes it in the variable asset.toc to the plug-in that renders the table of contents. See the source code of the auto-generated default templates _views/components/toc.html and _views/components/toc/level.html for details.

Inside all <h2> to <h6> elements that have been recognized a named anchor <a id="SLUG" name="SLUG" href="#"> is inserted, where SLUG is the slug text inside of the headline element. These named anchors are the targets of the links in the rendered table of contents.


Since it is an HTMLFilter plug-in, you configure it in the options for the plug-in. The command qgoda config should print something like this:

    - AnchorTarget
    - Generator
    - CleanUp
    - - TOC
      - content_tag
      - qgoda-content
      - toc_tag
      - qgoda-toc
      - start
      - 2
      - end
      - 6
      - template
      - components/toc.html

A more readable but equivalent form would look like this:

    - AnchorTarget
    - Generator
    - CleanUp
    - [TOC,
       content_tag, qgoda-content,
       toc_tag, qgoda-toc
       start, 2,
       end, 6,
       template, components/toc.html] 

The configuration variables are passed as key-value pairs. Their meaning is as follows:

The name of the tag that surrounds the content, defaults to qgoda-config.
The name of the placeholder tag of the table of contents, defaults to qgoda-toc.
The start level of the table of contents, defaults to 2 so that the 1st level will be built by <h2> elements.
The end level of the table of contents, defaults to 6 so that the last level will be built by <h6> elements.
The template for rendering the table of contents, defaults to components/toc.html (that is the file _views/components/toc.html).

You will find that it is rarely necessary to change any of the defaults.
