How to create a sidebar navigation like 'www.docs.streamlit.io'?

[Oscar]

Hi,
you can check this thread

New Component: Streamlit-antd-components，more widgets to extend streamlit!

When implementing the sidebar menu as you suggested, I encountered an issue: when I select ‘Apple,’ for example, it redirects to the specified page, but instead of rendering the page alongside the sidebar, it opens as a standalone page without the sidebar. To maintain sidebar functionality, I either need to reload the page or include a back button. Do you have any suggestions for addressing this issue?
