You can specify the pageType in the frontmatter metadata to use different layouts in the page. By default, the pageType of the document is doc, so the sidebar on the left and the outline on the right will appear by default. If you don't need these, you can set pageType to custom:
---
pageType: custom
---In rspress.config.ts, you can configure the content of the sidebar, for details, please refer to Sidebar Config.
