Add st.radio in st.column_config

Summary

Similar to having st.column_config.CheckboxColumn, I wonder if we can have the "single-select" st.radio in the column configuration.

Should not need a major rework.

Why?

Allow the option to select only one row at a time. This is helpful for us to develop a pseudo file explorer with st.data_editor.

How?

Add e.g. st.column_config.RadioColumn

Additional Context

st.radio manual. Why is this called "radio" btw?

SelectboxColumn is probably what you're looking for, see the docs here.

We don't plan to add radio buttons to data editor right now since a) the use case should already be covered by SelectboxColumn, b) radio buttons inside a table cell would look a bit weird I think, and c) it would require a significant amount of work since the underlying library does not support it. Will leave this issue open though to see if we get more upvotes.

Why is this called "radio" btw?

That's the standard term for this component in UI design. I actually had no idea why it's called radio though! Turns out, it's because they are named after actual radio receiver buttons:

Radio buttons were named after the physical buttons used on older radios to select preset stations[2][1] – when one of the buttons was pressed, other buttons would pop out, leaving the pressed button the only button in the "pushed in" position.

@ArthLeu Is your suggestion about adding a radio widget within every individual cell, or is it about allowing the user to only select a single row (which would be a bit related to #688)?

Sorry. To clarify, select one row at a time and return the row index. I know this is mentioned in #688 and addressed with Selectbox column. But with Selectbox it allows multiple selections.

What if we just want a single row to be selected at a time? It would be pretty time consuming for users to deselect the others manually.

And to deselect, we can't set False to a data_editor column either. I tested this with v1.25.0. User actions do triggers Streamlit rerun, but cell values don't get changed with e.g. df["Select"] = False.

So that's why I thought the radio column is still needed.

a long needed option to be able to select single row and get feedback on that to allow easier items selection for further processing and displaying info. Radio column where only single row can be selected might be a good way for st.data_editor, but what about st.dataframe?

This is definitely needed - I'm working on a supply chain app and various times wished for either this, or the ability to select a table row to prompt an action.
For example, selecting from item records with various details, to perform an action against one of them or populate a form view or chart in a another column, relating to one of those records...
It's standard in old school java and microsoft applications and is definitely going to be handy

Defneed single select option instead of checkboxcolumn.
the user experience is really friendly if the use case is to select one row at a time. as-is, user has to unselect and than select again.
it would be so much easier to develop the use case and improve the UX as well.

+1 to the single selection feature of data-editor. It is needed for our use case too.

[jrieke]

Ah sorry, I completely misunderstood this feature request in the beginning! If it's about selecting a single row from a dataframe, the good news is that this will be covered by the upcoming dataframe selections feature we're working on (#8411). See my update with link to demo app here (and I'll also give further updates on that other issue since it's the more general one).

[LukasMasuch]

We will release row & column selections for st.dataframe in the 1.35 release. Single-row selection can be activated like this:

selection = st.dataframe(df, on_select="rerun", selection_mode="single-row")

This will probably enable many use cases related to the radio column. It's unlikely that we will add a dedicated radio column to the column config in the near future. What's more likely is that we add the same selection support to st.data_editor as well.

Thank you!!! I don't know about others, but row selection is really one of the most wanted features for me.
