heading() renders an anchored heading: clicking the text jumps to the anchor, a ghost copy button appears on hover/focus and copies the #<id> link.

Levels

h2 and h3

From source

From registry

heading(2, 'Installation', { id: 'installation' });
heading(3, 'From source', { id: 'from-source' });
heading(3, 'From registry', { id: 'from-registry' });

heading(2, 'Create the account', { id: 'create-account', step: true });

Props

Option	Type	Description
level	1–6	Heading level (first argument).
text	string	Heading text (second argument).
id	string	Anchor id — also used by the copy-link button.
step	boolean	Marks the heading as a ClerkTOC step (data-cpd-step).

Notes

• The anchor link is href="#<id>"; the copy button copies the absolute location.origin + pathname + #<id> URL.
• step headings render with a step badge in the article and get step dots in the ClerkTOC rail.
