Looks good! Like the added documentation on connecting to the various databases

What does the roadmap towards session state look like? Can we expect it in any of the upcoming releases?

Hey @kmcgrady, great to see you adding new functionality and documentation all the time!

In terms of database documentation, is there any chance of a guide for connecting to Azure SQL Database? I’ve managed it locally, but am having difficulties getting it working on Streamlit sharing as mentioned here:

Installing ODBC Driver 17 for SQL Server in Streamlit sharing

Hi there, Love the tool that you’ve built. I’m trying to make my app that connects to a SQL database available via Streamlit sharing. It makes use of ODBC Driver 17 for SQL Server. Per here, I think the way to install this on Streamlit sharing(/Debian) is to add msodbcsql17 to a packages.txt file. I’m getting the following error though: Unable to locate package msodbcsql17 (NB: There’s a suggestion here that mssql-tools needs to be added to a packages.txt file, but the link above suggests…

Thanks!

st.selectbox with empty label st.selectbox('', ...) renders useless <label class="css-xxxxx xxxxxxx"></label> tag.
In v0.81.0, empty label didn’t rendered <label> tag.
Please check if this was intended improvement.
Thanks!

Hi @sethheon

Thank you for reaching out. It was intentional and included mainly for consistency since it’s included for every other widget. This change included the need to align widgets in columns more evenly.

I do advocate for a label for every widget as it is helpful from an accessibility background. Streamlit has more to improve here, but ensuring users put in a label for every widget is a start.
