I would like to display multiple plotly plots / folium maps on one single page and keep the output when pressing a button or when playing around with other widgets like a multi select box. I have heard about SessionState but I haven’t figured out yet how it works when using buttons.
When clicking on Map 2 the first map disappears because of a rerun of the whole script. Any idea how to tackle this challenge? I haven’t found a concrete button example.
The closest example that explains my issue is here:
import streamlit as st
from streamlit import session_state
import folium
from streamlit_folium import folium_static
def create_basic_map():
basic_map = folium.Map(location=[43.6532, -79.3832], tiles='openstreetmap', zoom_start=5)
folium.Marker([43.6532, -79.3832]).add_to(basic_map)
return folium_static(basic_map, width=500, height=300)
if 'key' not in session_state:
session_state.key = 0
if st.button('Map 1') or session_state.key == 1:
# session_state.key = True
create_basic_map()
st.write("Hello world 1")
if st.button("Map 2") or session_state.key == 2:
# session_state.key = True
create_basic_map()
st.write("Hello world 2")
if st.button("Map 3") or session_state.key == 3:
create_basic_map()
st.write("Hello world 3")
When I click on Map 3:
