fantastic news for the end of the year. However, I found the follwing behaviour and I wonder if it is a feature or a bug: I want to display a login button on the top-right. I have achieved this until now, by generating 2 columns and placed the button in the second column. Since version 1.3.0, if there is no content in column 0, the button will be placed in column 0 instead of column 1. The system also seems to react differently if the layout is set to wide, if I dont define the layout setting, it works as before. Placing an empty string in the first column is an easy enough workaround, just wanted to know it this behaviour is intended. Also: is there a better way for placing the login button to the upper-right? for example right-align widgets without any columns at all?

import streamlit as st

st.set_page_config(layout="wide")
cols = st.columns([9,1])

#if uncommented, it works
#with cols[0]:
#    st.write('')

with cols[1]:
    if st.button('Login'):
        pass

Hi @godot63 Thank you for bringing this up! I have confirmed it’s an issue. We have created an issue in out GitHub 1.3.0 bug - Empty columns are not respected in layouts · Issue #4216 · streamlit/streamlit · GitHub.

I have a solution for this but am working to get testing done and ensure it’s the correct change. With that, we can issue a patch release. Likely giving the timing, the patch will not be ready until the new year, but I will do my best to see if I can get it in sooner.

Thanks again for your help!

Hi Ken,

Thanks for getting back to me so soon. No rush on my side, as I mentioned, I have a workaround.

Cheers
