Hi guys I am new too streamlit and I extremely delighted to part of such a vibrant community. Currently I am working on an streamlit application and facing a problem. Well the thing is that i have multiple selectbox options and I am filtering my dataframe on the basis of these values. Currently i …

Hi @Hassan_waseem , and welcome to the Streamlit forum! :raised_hands: Please if you wouldn’t mind sharing the code, it would be easier for me review/debug. Best, Charly

import pandas as pd import streamlit as st data = {'feature_1': ['A','B','A','C','D','M','A','B','A','C'], 'feature_2': ['Zack','Hassan','Ali','Hassan','Hassan','Ali','Zack','Hassan','Hassan','Hassan'], 'feature_3': [0, 1, 0, 1, 1, 1, 0, 0, 1, 1], 'feature_4': [10,10,10,10…

Hi Hassan, I’ve had a chat internally and while it seems like something that is possible w.o any nested conditionals, I’ve yet to get my hand on a code snippet to share. I’m sure it’s possible to achieve similar results w/ the new state functionality, it you wanted to give it a try :slight_smile: …
