Summary
The function “use_container_width” of the button (st.button) does not work when the parameter “help” is used.
Obs.: using streamlit version 1.18.0
c1, c2, c3 = st.columns([1, 1, 1])
with c1:
st.button('button 1', use_container_width=True)
with c2:
st.button('button 2', use_container_width=True)
with c3:
st.button('button 3', use_container_width=True, help = 'example')
