22 Wide Layout, Page Tab Titles and Favicons

You may have noticed that Streamlit apps only seem to use part of the screen.

We can override this with the st.set_page_config(layout="wide") command.

Warning

This must be the first Streamlit command used on an app page (after importing streamlit)!

You must only set it once per page.

import streamlit as st

st.set_page_config(layout="wide")

st.title("App using full width")

st.write("Look at all this space we're using!")

22.1 Other settings in set_page_config

Within st.set_page_config, you can also

Set the page title that is shown in the browser tab
Set an icon that is used within the browser tab and if the user favourites the page
If using a sidebar, determines whether the sidebar starts opened, closed, or whether it’s determined by the width of the page
Set up links to ‘get help’, ‘report a bug’ and ‘about’ that will appear within the menu at the top-right of the app.

See the documentation for details on each of these.
