Summary
Hi all,
The segmented_control component is a fantastic new component that I think will be used a lot by Streamlit users.
However, I currently miss 1 option, that is to require a value. For example, now it is possible to provide a default value which can be unclicked.
Why?
In many use cases where segmented_control will be used in a single mode, the developer might want to force the user to select something.
How?
I propose to expand the segmented_control (and pills) API by adding an extra parameter 'required' . If required is True, a value must always be selected.
options = ["North", "East", "South", "West"]
selection = st.segmented_control(
"Directions",
options,
selection_mode="single",
required=True,
default="South",
)

Hi @jrieke! Thank you for the feedback. It is indeed related, but I think it is significantly easier to solve, as we won't need any front-end magic, I think. We only need to check if a required=True when the last item is deselected.
If y'all would be interested in this feature I could try to create a pull request for it. I think a lot of users would benefit from this!
