Usage
usage.tsx
import { MaskInput } from "@/registry/bases/radix/ui/mask-input";<MaskInput mask="phone" placeholder="Enter your phone number" />- Use it as a reference for wiring controlled MaskInput fields to React state.
- Use it when demonstrating phone, date, currency, credit-card, and percentage formatting in one UI.
- Use it as a form-layout example with accessible labels and responsive grid behavior.
Examples
Date input
Collect a birth date using the built-in date mask.
date-input.tsx
import { MaskInput } from "@/registry/bases/radix/ui/mask-input";<MaskInput mask="date" placeholder="Enter your birth date" />Euro currency input
Format currency using German locale conventions.
euro-currency-input.tsx
import { MaskInput } from "@/registry/bases/radix/ui/mask-input";<MaskInput mask="currency" currency="EUR" locale="de-DE" placeholder="0,00 €" />Percentage input
Restrict a percentage field to values from 0 through 100.
percentage-input.tsx
import { MaskInput } from "@/registry/bases/radix/ui/mask-input";<MaskInput mask="percentage" min={0} max={100} placeholder="0.00%" />Controlled credit-card input
Store the masked value in React state through onValueChange.
controlled-credit-card-input.tsx
import * as React from "react";import { MaskInput } from "@/registry/bases/radix/ui/mask-input";const [creditCard, setCreditCard] = React.useState("");<MaskInput mask="creditCard" value={creditCard} onValueChange={setCreditCard} placeholder="Enter your credit card number"/>Accessibility
- The demo associates every Label with its input through a matching htmlFor and id pair.
- React.useId creates unique field IDs, which helps prevent collisions when multiple demo instances render on the same page.
- The visible labels identify every field; helper text provides additional instructions for phone, date, currency, credit-card, and percentage fields.
- The helper paragraphs are not connected with aria-describedby in the demo, so additional form implementations should add that association when helper text is essential to completing the field.
