I’m trying to keep the selection in my st.selectbox accross pages.
When returning to the first (main) page, the selection must be set as before.

Bellow is a simplifyied code: I still have a jump between to choices when I change the selection.

Does anybody have an idea? I’m using Streamlit 1.37.

import streamlit as st


if __name__ == "__main__":
    TITLE = "Demo Streamlit App"
    st.set_page_config(layout="wide")

    st.sidebar.markdown("Home")
    st.title(TITLE)

    # initialize session state
    ss = st.session_state
    ss.setdefault("execution", {})
    if "first_execution" not in ss.execution:
        ss.execution["first_execution"] = True

    if "edition_mode" not in st.session_state:
        st.session_state.edition_mode = "New script"  # default value

    form1, _ = st.columns([1, 1])
    with form1:
        choices = [
            "New script",
            "Import script",
            "Load a script",
            "Delete a script",
        ]

        # Edition mode
        selected_mode = st.selectbox(
            label="Edition mode : ",
            options=choices,
            index=choices.index(st.session_state.edition_mode),
        )

        st.session_state.edition_mode = selected_mode

        st.write("---")

    st.write("---")

    ### Switch to the right app
    if ss.execution.get("switch_page"):
        st.switch_page("pages/01_Editor.py")

Thanks !
