Hi @joeysantia 👋 Apologies for the delay in following up on this PR. The change seems to be correct, I just left a note about a specific case we can fix, and after that it should be good to go 👐.

To explicitly pass the boolean checkbox value, we need to use the prop inputValue instead. Without this, we have this issue: when all items are selected, the checkbox doesnt appear as selected.
