Usage
usage.tsx
import PhoneInputFormDemo from "@/registry/bases/radix/examples/phone-input-form-demo";<PhoneInputFormDemo />- Use when collecting phone numbers alongside an explicitly selected country.
- Use as a reference for integrating PhoneInput with react-hook-form and Zod validation.
- Use when submitted phone data should be confirmed with a Sonner toast.
- Use when the country value needs to be stored separately from the phone number.
Examples
Standalone phone collection
Render the complete phone form in a settings or contact section.
standalone-phone-collection.tsx
import PhoneInputFormDemo from "@/registry/bases/radix/examples/phone-input-form-demo";export function ContactPhoneSection() { return <PhoneInputFormDemo />;}Account verification step
Use the example as the phone-number step in an account flow.
account-verification-step.tsx
import PhoneInputFormDemo from "@/registry/bases/radix/examples/phone-input-form-demo";export function AccountVerification() { return ( <section aria-labelledby="verification-title"> <h2 id="verification-title">Verify your phone</h2> <PhoneInputFormDemo /> </section> );}Responsive form container
Place the form inside a constrained container while retaining its full-width layout.
responsive-form-container.tsx
import PhoneInputFormDemo from "@/registry/bases/radix/examples/phone-input-form-demo";export function PhoneFormCard() { return ( <div className="mx-auto w-full max-w-md"> <PhoneInputFormDemo /> </div> );}Accessibility
- The phone field is associated with the visible “Phone Number” label through FormLabel.
- The form uses a native submit button with type="submit" and react-hook-form’s submit handling.
- The PhoneInput receives required, providing required-field semantics to the underlying control implementation.
- Validation feedback is rendered through FormMessage for the phone field.
- The supporting instruction is rendered with FormDescription and explains the expected country-code format.
- The country value is initialized to US and is updated through the PhoneInput country-change handler.
