# Parameter and Expandable `Parameter` renders the name/type/description row used throughout API reference content; `Expandable` wraps a nested set of them behind a "Show/Hide" toggle for a nested object's own properties — the same pattern used on this site's own OpenAPI-generated pages: The full name of the user Whether the user is over 21 years old ```mdx The full name of the user Whether the user is over 21 years old ``` Every field table across this documentation (`writedocs.json`'s own configuration pages included) is written with `Parameter` rather than a plain Markdown table — the same reason it exists here: a name, an optional type badge, an optional "required"/"default" label, and a description that can hold more than a single table cell's worth of prose. **`Parameter` props** Omit to render with no type badge. Shows a red "required" label. Shows a "default: ..." label. Any value works, including `default={10}` or `default={false}`. Shows an amber "deprecated" label and strikes the name through. Extra labels shown before the name, e.g. `pre={["readonly"]}`. Extra labels shown after the badges. `` and `` are the same row under Mintlify's names, with the same props. `ParamField` also takes the name from Mintlify's location props: ``, `query="limit"`, `body="email"`, or `header="Authorization"`. **`Expandable` props**
