Ability to set sidebar width

Source: https://discuss.streamlit.io/t/change-width-of-sidebar/5339/2

User would like to change the width of the st.sidebar.

Need to figure out (1) whether/when to implement this, and (2) what should the API be.

@jrieke I’m sharing your solution here, it’s been working great for me.

st.markdown(
    """
    <style>
    [data-testid="stSidebar"][aria-expanded="true"] > div:first-child {
        width: 500px;
    }
    [data-testid="stSidebar"][aria-expanded="false"] > div:first-child {
        width: 500px;
        margin-left: -500px;
    }
    </style>
    """,
    unsafe_allow_html=True,
)

Hi!

I am writing seeing this got closed after enabling the user to resize the sidebar.

I would like to have the ability to resize programatically the sidebar, or at least be able to provide a default value. For instance when using iframes or https://github.com/andfanilo/streamlit-drawable-canvas , they get cut off and the user has to manually resize the sidebar in order to see everything.

Is having sidebar size configurable still in the work? Otherwise, should I open a different issue than this one?
