Thanks for contributing to Streamlit! 🎈

Please make sure you have read our Contributing Guide. You can find additional information about Streamlit development in the wiki.

The review process:

  1. Initial triage: A maintainer will apply labels, approve CI to run, and trigger AI-assisted reviews. Your PR may be flagged with status:needs-product-approval if the feature requires product team sign-off.

  2. Code review: A core maintainer will start reviewing your PR once:

    • It is marked as 'ready for review', not 'draft'
    • It has status:product-approved (or doesn't need it)
    • All CI checks pass
    • All AI review comments are addressed

We're receiving many contributions and have limited review bandwidth — please expect some delay. We appreciate your patience! 🙏

Pull request overview

This PR updates the st.navigation docstring documentation for the expanded parameter to clarify when the sidebar navigation can collapse and how changes to expanded behave across reruns.

Changes:

  • Clarifies that the expanded collapse/expand behavior only applies when the sidebar has additional content below the nav menu.
  • Rewords the descriptions of expanded=False, expanded=True, and integer values, including rerun behavior when expanded changes.

@lukasmasuch I can't merge any of the docs PR anymore since I'm an external contributor. Please go ahead and merge them. If theses are after a release cut, they can be cherry picked.
