You can set use_container_width for st.image. use_column_width is deprecated.

… but the default value is False

---

Sidenote: if you find yourself always adding use_container_width to buttons, images, dataframes, etc., there is this small patch to make all components to follow a single default. See an example:

st default width

[mathcatsand]

If you don’t set width or use_container_width, it will use the image’s natural size (up to the width of the parent container). So if the image is large enough, it will naturally be full width. If it defaulted to full width, then a smaller image would be upscaled which is unlikely to be what people want…

but the default value is False

Hey, we discussed setting it to True by default. But as Debbie pointed out, this might be weird for small images (e.g. a company logo), so we kept it at False for now. We will change the default for other elements like dataframes and charts though.

When would be Native authentication support release?

Interested in this as well

[Goyo]

It is planned for this quarter in the roadmap. Currently under development.

Authentication & st.user Development
Add authentication to your Streamlit app with a config file, and check via st.user which user is logged in.

Nice, I see that in the roadmap as well

st.pills is a nice addition !
Unfortunately, you can’t prevent a pill from being deselected for a language selection for example.
I hope to see this option added in the next update.

[Goyo]

Same for st.segmented_control. Would be nice to have a “strict_single” selection mode that makes them work the same as radio buttons.

[Ido_Lapid]

What is the difference between st.segmented_control and st.pills. and how it affects their use?
