Not a single form field has a label. These designs are not usable and the patterns presented should be discouraged.

I suggest adding a validation check like Nu Validator, aXe, lighthouse, etc. to show all the places this markup is invalid.

Nothing happens at the moment when clicking the form help: https://tabler-react.com/form-elements (It's next to the zip code box).

<Form.Help message={<><p>ZIP Code must be US or CDN format. You can use an extended ZIP+4 code to determine address more accurately.</p><p class="mb-0"><a href="#">USP ZIP codes lookup tools</a></p></>} />
