• I have provided sufficient information below to help reproduce this issue.

Summary

Since Streamlit 1.52 (cool release by the way! ❤️ ), with st.navigation(position="top"), the navigation appears in both the top and sidebar.

Reproducible Code Example

import streamlit as st

def a():
    st.header("Header A")

def b():
    st.header("Header B")

st.sidebar.header("Sidebar Header")
st.navigation((a, b), position="top").run()

Steps To Reproduce

Try the above code example.

Expected Behavior

From the documentation:

If this is "top", the navigation appears in the top header of the app.

The navigation should only appear in the top bar, as it did in Streamlit 1.51.

Current Behavior

Since Streamlit 1.52, the navigation appears in both the top and sidebar.

Is this a regression?

• Yes, this used to work in a previous version.

Debug info

• Streamlit version: 1.52.0
• Python version: 3.11.9
• Operating System: MacOS
• Browser: Chrome

Additional Information

The position="sidebar" and position="hidden" seem to behave as expected.
