Expand One Grid Row Only at a Time with React

Hello, Raef,

The expanded state of the details is part of the data.

I can suggest on the onExpandChange event to set the expanded state to expanded on the currently clicked detail and set the expanded field to false to all other items.

I made an example showcasing this:

I hope this is helpful.
