Textarea

Textarea is a form component that allows the user to enter a sizeable amount of multi-line plain text.

Import

import { Textarea } from '@contentful/f36-components';
// or
import { Textarea } from '@contentful/f36-forms';

Examples

Using as a controlled input

Controlled components in React are those in which form data is handled by the component’s state.

For using the Textarea as a controlled input, you need to:

  • Pass value property, with this property it will already be a controlled component;
  • Pass onChange handler, so you can use it to update the value of the input;

Using as an uncontrolled input

Uncontrolled components are those for which the form data is handled by the DOM itself. “Uncontrolled” refers to the fact that these components are not controlled by React state.

You can use the Textarea as an uncontrolled input, for that you can:

  • Set the defaultValue property, it will ensure that the initial value of the input is set.
  • Don't set the value as it will make the input controlled.

Using outside of forms

When Textarea is used outside of form (without FormControl) and has no <label> associated with it, you need to specify aria-label.

Accessibility

  • To ensure accessibility, provide a name prop
  • In case the input is required, use isRequired prop
  • If you are using this component in a form, provide validation to the input and use isInvalid to control the error state of Textarea. Also show meaningful error messages with the ValidationMessage component.
