st.set_page_config

Configures the default settings of the page.

Note

This must be the first Streamlit command used on an app page, and must only be set once per page.

Function signature[source]
st.set_page_config(page_title=None, page_icon=None, layout="centered", initial_sidebar_state="auto", menu_items=None)
Parameters
page_title (str or None)	The page title, shown in the browser tab. If None, defaults to the filename of the script ("app.py" would show "app • Streamlit").
page_icon (Anything supported by st.image, str, or None)	The page favicon. If `page_icon` is `None` (default), the favicon will be a monochrome Streamlit logo. In addition to the types supported by `st.image` (like URLs or numpy arrays), the following strings are valid: A single-character emoji. For example, you can set `page_icon="🦈"`. An emoji short code. For example, you can set `page_icon=":shark:"`. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes. The string literal, `"random"`. You can set `page_icon="random"` to set a random emoji from the supported list above. Emoji icons are courtesy of Twemoji and loaded from MaxCDN. An icon from the Material Symbols library (outlined style) in the format `":material/icon_name:"` where "icon_name" is the name of the icon in snake case. For example, `icon=":material/thumb_up:"` will display the Thumb Up icon. Find additional icons in the Material Symbols font library. Note Colors are not supported for Material icons. When you use a Material icon for favicon, it will be black, regardless of browser theme.
layout ("centered" or "wide")	How the page content should be laid out. Defaults to "centered", which constrains the elements into a centered column of fixed width; "wide" uses the entire screen.
initial_sidebar_state ("auto", "expanded", or "collapsed")	How the sidebar should start out. Defaults to "auto", which hides the sidebar on small devices and shows it otherwise. "expanded" shows the sidebar initially; "collapsed" hides it. In most cases, you should just use "auto", otherwise the app will look bad when embedded and viewed on mobile.
menu_items (dict)	Configure the menu that appears on the top-right side of this app. The keys in this dict denote the menu item you'd like to configure: "Get help": str or None The URL this menu item should point to. If None, hides this menu item. "Report a Bug": str or None The URL this menu item should point to. If None, hides this menu item. "About": str or None A markdown string to show in the About dialog. If None, only shows Streamlit's default About text. The URL may also refer to an email address e.g. `mailto:john@example.com`.

Example

import streamlit as st

st.set_page_config(
    page_title="Ex-stream-ly Cool App",

    initial_sidebar_state="expanded",
    menu_items={

        'Report a bug': "https://www.extremelycoolapp.com/bug",

    }
