Inline TOC

Each Markdown document displays a tab of content on the top-right corner.

But it is also possible to display an inline table of contents directly inside a markdown document, thanks to MDX.

Full table of contents

The toc variable is available in any MDX document, and contains all the headings of a MDX document.

By default, only h2 and h3 headings are displayed in the TOC. You can change which heading levels are visible by setting minHeadingLevel or maxHeadingLevel.

import TOCInline from '@theme/TOCInline';

<TOCInline toc={toc} />;

Custom table of contents

The toc props is just a list of table of contents items:

type TOCItem = {
  value: string;
  id: string;
  children: TOCItem[];
  level: number;
};

You can create this TOC tree manually, or derive a new TOC tree from the toc variable:

import TOCInline from '@theme/TOCInline';

<TOCInline
  toc={
    // Only show 3th and 5th top-level heading
    [toc[2], toc[4]]
  }
/>;

  • Example Subsection 1 b
  • Example Subsection 1 c
• Example Section 3
  • Example Subsection 3 a
  • Example Subsection 3 b
  • Example Subsection 3 c
