Can we configure MultiSelectGride widget accept only one selection?

I use MultiSelectGrid widget for my customers to book a meeting. How can we configure this widget so that it accepts only one selection

Unfortunately, it's not possible to set a single selection limit on a MultiSelect Grid widget. You might want to make use of something else instead like a single choice field, or Button Radios widget.

Here is a screenshot with the Button Radios widget:

Thanks.
