Add an example on how to achieve live filtering

[bartbroere]

📚 Context

I decided to propose this change to the documentation since I find this way of creating filters useful myself.

There are some entries on the Streamlit blog describing how to filter dataframes, but a more simple example in the official documentation also felt right. In References below I link the two blog posts I looked at, which felt like a bit too much code for people with relatively simple filtering needs 😅 .

🧠 Description of Changes

I added a chapter to the "Advanced features > DataFrames" page on how to live filter a dataset.

💥 Impact

Just documentation so I would choose:

• Small

🌐 References

• Make dynamic filters in Streamlit and show their effects on the original dataset
• Auto-generate a dataframe filtering UI in Streamlit with filter_dataframe!

Hi @bartbroere! Sorry it's taken so long to get to this. I think a live filtering example is something we'll want as its own tutorial instead of added to the guide/conceptual page. I'm working on some major restructuring of the docs which will create a much cleaner and discoverable place for these small tutorials. I'm happy to get it added to the Knowledge Base now if you want, but I'll have a much better place to put it probably this quarter. 😄

Hi! That sounds like a nice improvement. No worries about the delay. I'll let you and your organisation decide where to put it, and when.

Feel free to work on my branch, ask me to move something, or just copy/paste anything from the diff.
