+### Collapse playground sections
+
+Collapse the request sections of the API playground by default using `x-mint: playground` with `expandSections: false` on any operation. When collapsed, readers expand only the sections they want to interact with, like Authorization, Headers, Query, Path, Body, and Server. Sections are expanded by default when `expandSections` is not set.

 ### Parameter pills
 
 Annotate parameters in the API reference and playground with custom pill labels using `x-mint.pre` and `x-mint.post` on any schema. Pills defined with `x-mint.pre` render before the parameter name, and pills defined with `x-mint.post` render after it, alongside Mintlify's built-in pills like `required`, `read-only`, and `write-only`.
