Ensure the labels are precise and concise. Labels should only describe the text field they are associated with, and they must be visible. If you cannot use the
label prop, ensure the alternative label's
htmlFor attribute matches the TextArea's
id. Labels are properly associated when clicking the label focuses the TextArea.
When providing a validation message, make sure the instructions are clear and help users complete the field. For example, "This field is required to submit". In addition, use the helper text to provide instructions to help users understand how to complete the text field or to indicate any needed input, allowed formats, timing limitations, or other pertinent information.
These practices give users of assistive technologies more information about the form, helping them to fill it out.
TextArea has conventional keyboard support.
- Users relying on the keyboard expect to move focus to each TextArea by using the tab key or shift+tab when moving backwards.
disabledwill prevent TextArea from receiving keyboard focus or input.
TextArea intentionally lacks support for autofocus. Generally speaking, autofocus interrupts normal page flow for screen readers making it an anti-pattern for accessibility.
TextArea is commonly used as an input in forms alongside submit buttons. In these cases, users expect that pressing Enter or Return with the input focused will submit the form.
Out of the box, TextArea doesn't expose an
onSubmit handler or individual key event handlers due to the complexities of handling these properly. Instead, developers are encouraged to wrap TextField in a
<form> with an
Be sure to localize
TextArea will expand to fill the width of the parent container by default.
Whenever you want to provide more information about a form field, you should use
In some cases, the label for a TextArea is represented in a different way visually, as demonstrated below. In these instances, you can set
labelDisplay="hidden" to ensure TextArea is properly labeled for screen readers while using a different element to represent the label visually.
TextArea can be in read-only mode in order to present information to the user without allowing them to edit the content. Typically this variation is used to show content or information that the user does not have permission or access to edit.
TextArea can be disabled to indicate the user is unable to interact with it, either by mouse or keyboard. Disabled fields do not need to pass contrast requirements, so do not use a
disabled TextArea to present information to the user (use
A TextArea can display its own error message.
To use our errors, simply pass in an
errorMessage when there is an error present and we will handle the rest.

You can include Tag elements in the input using the
Note that the
TextArea component does not internally manage tags. That should be handled in the application state through the component's event callbacks. We recommend creating new tags on enter key presses, and removing them on backspaces when the cursor is in the beginning of the field. We also recommend filtering out empty tags.
This example showcases the recommended behavior.
