details

Renders a collapsible details and summary block, closed by default

Either call form works, and both produce identical HTML.

Note

This shortcode shadows Hextra’s details, so its behavior differs from the upstream one of the same name. See the Hextra shortcodes guide for the baseline.

Parameters

Name	Type	Required	Default	Description
`title`	string	yes	—	The clickable summary heading. Supports Markdown.
`open`	bool	no	`false`	Pass open=“true” to render the block expanded on page load.

Example

{{< details title="Show the full output" >}}
The body appears only after the reader clicks the summary.
{{< /details >}}

Rendered output

Show the full output

The body appears only after the reader clicks the summary.

Notes

The default state is closed, which deliberately inverts Hextra’s default-open behavior. Collapsed-by-default is the conservative choice for docs: a details block means “click to reveal extra info”, not “always visible”.

Hextra’s upstream takes the inverted closed="true" to close. This shortcode does not read that param. Existing consumer content uses open="true" to open, and a stray closed="true" becomes a no-op that still renders correctly, since closed is already the default.
