# `showSchemaCatalogLinks`

Display links with a reference to a specific schema in an OpenAPI file.
The reference can be used as a `$ref` value in other OpenAPI files within the same project.
These links are always displayed for OpenAPI requests and are shown for schemas when the [`schemaDefinitionsTagName`](/docs/platform/config/openapi/schema-definitions-tag-name) option is configured.

The **code** showSchemaCatalogLinks  is not available in Redoc Community Edition.

## Options

| Option | Type | Description |
| --- | --- | --- |
| showSchemaCatalogLinks | boolean | Displays links to schemas and requests on an OpenAPI page. These links can be used as `$ref` value in other OpenAPI files within the same project. Default: `false`. |
