When using st.chat_input inside st.columns(), chat box moves up. How to keep it stuck to the bottom?

If you user st.chat_input in the main body of the app, it will pin to the bottom. If you use it inside any kind of container, it will be inline like any other element. This is expected. A parameter to float the chat input within a container has not been implemented yet.

In the mean time, use a fixed-height container above your chat input to hold messages.

with st.container():
    history = st.container(height=400)
    prompt = st.chat_input("Write something")
