Thank you very much for the review. I made the following changes 1. I removed the array is populated check 2. I made it so that you can only have each user once. 3. I added the key to the mapped element. Thanks again.

Thank you for the review! Here is my V2. What i did differently was instead of having a state for each dropdown, i have a single state with an isOpen property and i modify that single state instead. Although i think my original is probably better practice in the long run as its way more intuitive to modify only the state of the component itself. Let me know if this is what you had in mind.

Done. Added the sorting feature here too.

Done. Let me know what you think. I also changed sort to toSorted because i realized that sort will mutate the caller, which might modify state directly.
