The showExtensions option displays specification extensions ('x-' fields). Extensions used by Redoc are ignored. The value can be boolean or an array of strings with names of extensions to display. When used as boolean and set to true, all specification extensions are shown.
Custom extensions are rendered only in the request details section and in individual field details; they do not appear elsewhere in the UI.
| Option | Type | Description |
|---|---|---|
| showExtensions | string[] | boolean | Specify which specification extensions ('x-' fields) to display, or use true to show them all. Default value is false which does not display any extensions. |
