Save checkbox selection session state

Using Streamlit
, ,
1

Hey there :grin:!
I am currently working on a webpage where users can go through a list and select with checkboxes whether a particular point is relevant to them or not. Unfortunately, I am unable to save the checkbox selections in the session_state, so the selections remain visible even after a page refresh. Could you help me with this?

def update_state_generic(key_prefix, gruppe, unterthema, auswahl):
   key = f"{key_prefix}_{gruppe}_{unterthema}"
   st.session_state[key] = auswahl

def create_expander(thema, unterthemen, state_key):
  with st.expander(thema):
    col_text, col_rb1, col_rb2, col_rb3 = st.columns([6, 1, 1, 1])
    if thema == unterthemen_esrse1:
        col_text.write("**" + "Klimawandel" + "**")
    elif thema == unterthemen_esrse2:
        col_text.write("**" + "Umweltverschmutzung" + "**")
    elif thema == unterthemen_esrse3:
        col_text.write("**" + "Wasser- & Meeresressourcen" + "**")
    elif thema == unterthemen_esrse5:
        col_text.write("**" + "Kreislaufwirtschaft" + "**")
    elif thema == unterthemen_esrsg1:
        col_text.write("**" + "Unternehmenspolitik" + "**")

    col_rb1.write("Wesenlich")
    col_rb2.write("Teilweise Wesentlich")
    col_rb3.write("Nicht Wesentlich")
    for unterthema in unterthemen:
        col_text, col_rb1, col_rb2, col_rb3 = st.columns([6, 1, 1, 1])
        with col_text:
            st.markdown(f"<p style='font-family:Source Sans Pro;'>• {unterthema}</p>", unsafe_allow_html=True)
        for i, option in enumerate(optionen):
            col = [col_rb1, col_rb2, col_rb3][i]
            with col:
                checkbox_key = f"{state_key}_{unterthema}_{option}"
                checkbox_value = st.session_state.get(checkbox_key, False)
                # Hier passen wir den Aufruf an die erwartete Signatur von update_state_generic an
                st.checkbox("Select", key=checkbox_key, value=checkbox_value, on_change=update_state_generic, args=(state_key, '', unterthema, option), label_visibility="collapsed")

Perhaps you can handle the session status updates separately, perhaps by adding a submit button or other mechanism to trigger the updates.

import streamlit as st

# Define your data
themen = ["Thema 1", "Thema 2", "Thema 3"]
unterthemen_esrse1 = ["Unterthema 1", "Unterthema 2", "Unterthema 3"]
optionen = ["Wesenlich", "Teilweise Wesentlich", "Nicht Wesentlich"]

# Function to update session state
def update_state_generic(key_prefix, gruppe, unterthema, option, auswahl):
    key = f"{key_prefix}_{gruppe}_{unterthema}_{option}"
    st.session_state[key] = auswahl

# Function to create expander
def create_expander(thema, unterthemen, state_key):
    with st.expander(thema):
        for unterthema in unterthemen:
            st.write(f"### {unterthema}")
            for option in optionen:
                checkbox_key = f"{state_key}_{unterthema}_{option}"
                checkbox_value = st.session_state.get(checkbox_key, False)
                checkbox_value = st.checkbox(option, key=checkbox_key, value=checkbox_value)
                update_state_generic(state_key, '', unterthema, option, checkbox_value)

# Usage
create_expander("ESR/SE", unterthemen_esrse1, "esrse")

# code to send the information .....

@AndreeS98 did you find any solution for preserving the row state, except for having the new button?
