Provide a way to change the default width of sidebar

Problem

I would like to be able to change the width of the sidebar. In the previous version, the method mentioned in this https://github.com/streamlit/streamlit/issues/2058#issuecomment-816989601 worked well to solve my problem.

However, after the update, sidebar became draggable, but the above method no longer works. I also did not find a parameter where I can change the default width. Please forgive me if I am missing something

Solution

MVP: Provide a parameter in st.set_page_config to control the default sidebar width.

+1 to this request @jrieke.

Setting a fixed sidebar width is quite important. If a user makes sidebar too narrow, everything in it starts “word-wrapping”. This happening to 1 widget or element in sidebar is bearable, but with a few widgets or elements in the sidebar (a very common situation in Streamlit apps), it gets ugly fast.

For example, sometimes we want this sidebar width to match the width needed to display a header, subheader, text, or button with a “longer than usual label” in a single line (instead of “word-wrapping” and continuing on a second line).

Same here. I jumped into 1.14 from 1.11. I do not particularly care for the manual resizing, but the sidebar is now too narrow for the content I had there before.
