A text area serves as a multi-line, plain-text editing interface.
A TextArea uses the following components.
A text area in a disabled state shows that an input field exists, but is not available in that circumstance. This can be used to maintain layout continuity and communicate that a field may become available later.
The isReadOnly prop makes the text area's text content immutable. Unlike isDisabled, the text area remains focusable and the contents can still be copied. See the MDN docs for more information.
A text area can be displayed in an error state to indicate that the user input is invalid.
A text area can vary in size. The height is determined by the number of rows. Each size has a unique font size, resulting in varying heights across different sizes.
If a visible label isn't specified, an aria-label must be provided to the text area for accessibility. If the field is labeled by a separate element, an aria-labelledby prop must be provided using the ID of the labeling element instead.
A text area can have a description using the HelperMessage component to provide additional context to the user.
A character count can be displayed below the input. The character count is based on the maxLength prop. If the maxLength prop is not set, the character count will not be displayed.
To exceed the max length, set the allowExceedingMaxLength prop to true – default is false. When the character count is displayed, it turns red if the max length is exceeded.
Note: If allowExceedingMaxLength is set, a character count is required to be set as well.
The rows prop can be used to set the height of the text area and should be used in favor of the height prop. One row is equivalent to the height of one line of text.
The maxRows prop can be used to set the maximum height of the text area and should be used in favor of the maxHeight prop.
It differs from the rows prop in that it will not set the initial height of the text area.
The resizeMode prop can be used to set the resize behavior of the text area.
The default behavior is none, which prevents the user from resizing the text area.
The vertical behavior allows the user to resize the text area vertically.
True to display the number of remaining allowed characters on the right of the input. Requires a valid value in the "maxLength" prop.
The maximum number of visible text lines before displaying a scrollbar.
The placeholder text when the TextArea is empty.

See MDN.
The size of the TextArea.
If true, the TextArea will take all available width.
This should only be used with the showCharacterCount prop.
If true, the TextArea will allow the text to go over the max length, but it will add an error look to the character count.
The resize mode value of the TextArea. It's equivalent to the CSS resize property.
A ref for the HTML textarea element.
Whether the required state should be shown as an asterisk or a label, which would display (Optional) on all non required field labels.
The props for the InputGroup.
The props for the RemainingCharacterCount.
The inline style for the element. A function may be provided to compute the style based on component state.

Whether to use native HTML form validation to prevent form submission when the value is missing or invalid, or mark the field as required or invalid via ARIA.
Whether the input is disabled.
Whether the input can be selected but not changed by the user.
Whether user input is required on the input before form submission.
Whether the value is invalid.
A function that returns an error message if a given value is invalid.
Validation errors are displayed to the user when the form is submitted
if validationBehavior="native". For realtime validation, use the isInvalid
prop instead.
Whether the element should receive focus on render.

Hints at the type of data that might be entered by the user while editing the element or its contents. See MDN.

The CSS className for the element. A function may be provided to compute the class based on component state.
The children of the component. A function may be provided to alter the children based on component state.
Handler that is called when the element receives focus.
Handler that is called when the element loses focus.
Handler that is called when the element's focus status changes.
Handler that is called when a key is pressed.
Handler that is called when a key is released.
Handler that is called when the user copies text. See MDN.
Handler that is called when the user cuts text. See MDN.
Handler that is called when the user pastes text. See MDN.
Handler that is called when a text composition system starts a new text composition session. See MDN.
Handler that is called when a text composition system completes or cancels the current text composition session. See MDN.
Handler that is called when a new character is received in the current text composition session. See MDN.
Handler that is called when text in the input is selected. See MDN.
Handler that is called when the input value is about to be modified. See MDN.
Handler that is called when the input value is modified. See MDN.
Identifies the currently active element when DOM focus is on a composite widget, textbox, group, or application.
Indicates whether inputting text could trigger display of one or more predictions of the user's intended value for an input and specifies how predictions would be presented if they are made.
Indicates the availability and type of interactive popup element, such as menu or dialog, that can be triggered by an element.
Defines a string value that labels the current element.
Identifies the element (or elements) that labels the current element.
Identifies the element (or elements) that describes the object.
Identifies the element (or elements) that provide a detailed, extended description for the object.

Identifies the element that provides an error message for the object.
A slot name for the component. Slots allow the component to receive props from a parent component.
An explicit null value indicates that the local props completely override all props received from a parent.
