TextArea

Simple Example

Note: While a base textarea component is provided in this package, it is not accessible when used as is. It should be used in tandem with FormField to be made fully accessible (see below).

import * as React from 'react';
import TextArea from '@workday/canvas-kit-react-text-area';

<TextArea placeholder="Placeholder" value={this.state.value} onChange={() => {}} />;

Accessible Example

import * as React from 'react';
import TextArea from '@workday/canvas-kit-react-text-area';
import FormField from '@workday/canvas-kit-react-form-field';

// Accessible default state
<FormField label="My Field" inputId="my-textarea-field">
  <TextArea placeholder="Placeholder" value={this.state.value} onChange={() => {}} />;
</FormField>

// Accessible error state
<FormField
  label="My Field"
  inputId="my-textarea-field"
  hintText="Helpful text to resolve error"
  hintId="my-textarea-field-error"
  error={FormField.ErrorType.Error}
>
  <TextArea placeholder="Placeholder" value={this.state.value} onChange={() => {}} />;
</FormField>

If use inside a FormField doesn't work for your use case, you can use the aria-labelledby attribute.

import * as React from 'react';
import TextArea from '@workday/canvas-kit-react-text-area';
<label id="123">Label</label>
...
<TextArea placeholder="Placeholder" value={this.state.value} onChange={() => {}} aria-labelledby="123" />;
