# Expandables

Use `Expandable` when a page needs optional detail without creating a full accordion list.

<Expandable title="Show advanced options" defaultOpen>
  Expandables work well for secondary details, object internals, or long examples that should not dominate the page.

  * Nested markdown is supported
  * Code blocks are supported

  ```json
  { "advanced": true, "source": "holocron" }
  ```
</Expandable>

## Holocron differences

* Holocron currently supports `title` and `defaultOpen`.
* This is a simpler disclosure primitive than Mintlify's richer schema-documentation examples, but it covers the common authoring pattern.
