I tried to improve this but failed 😣. TypeScript is one of the reasons I try to avoid components with union value type 🥲. It's really hard to get it right.
Thanks for working on this!

I feel you, types in this PR tested my patience 😅

I suggest to add a couple of more demos:
#### Selected value appearance
Display avatars of selected users end with "x friends".
#### Form submission
Show what the value looks like after submitted a form.

I think it looks better than outlined and success.

It is strange that formJson.pets is a string, not an array. Is this expected?
I got "[\"dog\"\" instead of ["dog"].

When you console.log On logging formJson.pets it indeed prints array, so issue you described maybe have to do something with alerttypeof formJson.pets i'm getting type as string. Ideally It should be object, let me check

Is this expected?
Yes, this is expected because if Select has multiple prop then value of hidden input is stringified. so users need to do JSON.parse to convert it to array.

So I've modified demo and parsed string to array. Now demo is looking good
