| `categoryLinkSource` | `string` | `null` | Defines what source to use for rendering category link pages when grouping paths by tag. <br/><br/>The supported options are as follows: <br/><br/> `tag`: Sets the category link config type to `generated-index` and uses the tag description as the link config description. <br/><br/>`info`: Sets the category link config type to `doc` and renders the `info` section as the category link (recommended only for multi/micro-spec scenarios). <br/><br/>`none`: Does not create pages for categories, only groups that can be expanded/collapsed. |

Describe the problem

The documentation indicates categoryLinkSource supports a none option, however, the plugin only accepts [tag, info, auto]

[ValidationError]: "config.api.sidebarOptions.categoryLinkSource" must be one of [tag, info, auto]

Suggested fix

Can we confirm if this functionality is no longer supported, and if so, remove this from the documentation?

If this option is no longer available, I would love to see this as a feature request. I am trying to remove category index page links from my sidebar and this would have been a huge help.
