selectbox on sidebar in streamlit only display the label caption. it doesnt display the drop down menu with the values but if I modify the code and remove 'sidebar', it works fine on the main page.
example:
st.sidebar.selectbox('select stock',['APPL', 'GOOG'])
will only display 'select stock' on the sidebar without the drop-down menu but
st.selectbox('select stock',['APPL', 'GOOG'])
will work fine on the main page
why is this?
