Signature Pad

A component that allows users to draw a signature using a signature pad.

Signature

Anatomy

To set up the signature pad correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the Signature Pad component in your project. Let's take a look at the most basic example:

import { SignaturePad } from '@ark-ui/react'

export const Basic = () => (
  <SignaturePad.Root>
    <SignaturePad.Label>Sign below</SignaturePad.Label>
    <SignaturePad.Control>
      <SignaturePad.Segment />
      <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
      <SignaturePad.Guide />
    </SignaturePad.Control>
  </SignaturePad.Root>
)

Image Preview

After the user draws a signature, you can display a preview of the signature as an image. This is useful when you want to show the user a preview of the signature before saving it.

import { useState } from 'react'
import { SignaturePad } from '@ark-ui/react'

export const ImagePreview = () => {
  const [imageUrl, setImageUrl] = useState('')

  return (
    <>
      <SignaturePad.Root
        onDrawEnd={(details) => details.getDataUrl('image/png').then((url) => setImageUrl(url))}
      >
        <SignaturePad.Label>Sign below</SignaturePad.Label>
        <SignaturePad.Control>
          <SignaturePad.Segment fill="orange" />
          <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
          <SignaturePad.Guide />
        </SignaturePad.Control>
      </SignaturePad.Root>

      {imageUrl && <img src={imageUrl} alt="Signature" />}
    </>
  )
}

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of a signature pad. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

import { Field, SignaturePad } from '@ark-ui/react'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <SignaturePad.Root>
      <SignaturePad.Label>Label</SignaturePad.Label>
      <SignaturePad.Control>
        <SignaturePad.Segment />
        <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
        <SignaturePad.Guide />
      </SignaturePad.Control>
    </SignaturePad.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)
