The <textarea> HTML element represents a multi-line plain-text editing control, useful when you want to allow users to enter a sizeable amount of free-form text, for example a comment on a review or feedback form.

Fields

accesskey: Option<&'life str>

Provides a hint for generating a keyboard shortcut for the current element. This attribute consists of a space-separated list of characters. The browser should use the first one that exists on the computer keyboard layout.

autocapitalize: Option<&'life str>

Controls whether and how text input is automatically capitalized as it is entered/edited by the user. It can have the following values:

• off or none, no autocapitalization is applied (all letters default to lowercase)
• on or sentences, the first letter of each sentence defaults to a capital letter; all other letters default to lowercase
• words, the first letter of each word defaults to a capital letter; all other letters default to lowercase
• characters, all letters should default to uppercase

autocomplete: Option<&'life str>

This attribute indicates whether the value of the control can be automatically completed by the browser. Possible values are:

• off: The user must explicitly enter a value into this field for every use, or the document provides its own auto-completion method; the browser does not automatically complete the entry.
• on: The browser can automatically complete the value based on values that the user has entered during previous uses.

If the autocomplete attribute is not specified on a <textarea> element, then the browser uses the autocomplete attribute value of the <textarea> element's form owner. The form owner is either the <form> element that this <textarea> element is a descendant of or the form element whose id is specified by the form attribute of the input element. For more information, see the autocomplete attribute in <form>.

autocorrect: Option<&'life str>

A string which indicates whether to activate automatic spelling correction and processing of text substitutions (if any are configured) while the user is editing this textarea. Permitted values are:

on

Enable automatic spelling correction and text substitutions.

off

Disable automatic spelling correction and text substitutions.

autofocus: Option<bool>

This Boolean attribute lets you specify that a form control should have input focus when the page loads. Only one form-associated element in a document can have this attribute specified.

class: Option<&'life str>

A space-separated list of the classes of the element. Classes allow CSS and JavaScript to select and access specific elements via the class selectors or functions like the method Document.getElementsByClassName().

cols: Option<&'life str>

The visible width of the text control, in average character widths. If it is specified, it must be a positive integer. If it is not specified, the default value is 20.

contenteditable: Option<&'life str>

An enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:

• true or the empty string, which indicates that the element must be editable;
• false, which indicates that the element must not be editable.

contextmenu: Option<&'life str>

The id of a <menu> to use as the contextual menu for this element.

data: Option<BTreeMap<&'life str, &'life str>>

Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.

dir: Option<&'life str>

An enumerated attribute indicating the directionality of the element's text. It can have the following values:

• ltr, which means left to right and is to be used for languages that are written from the left to the right (like English);
• rtl, which means right to left and is to be used for languages that are written from the right to the left (like Arabic);
• auto, which lets the user agent decide. It uses a basic algorithm as it parses the characters inside the element until it finds a character with a strong directionality, then it applies that directionality to the whole element.

disabled: Option<bool>

This Boolean attribute indicates that the user cannot interact with the control. If this attribute is not specified, the control inherits its setting from the containing element, for example <fieldset>; if there is no containing element when the disabled attribute is set, the control is enabled.

draggable: Option<&'life str>

An enumerated attribute indicating whether the element can be dragged, using the Drag and Drop API. It can have the following values:

• true, which indicates that the element may be dragged
• false, which indicates that the element may not be dragged.

enterkeyhint: Option<&'life str>

Hints what action label (or icon) to present for the enter key on virtual keyboards.

exportparts: Option<&'life str>

Used to transitively export shadow parts from a nested shadow tree into a containing light tree.

form: Option<&'life str>

The form element that the <textarea> element is associated with (its "form owner"). The value of the attribute must be the id of a form element in the same document. If this attribute is not specified, the <textarea> element must be a descendant of a form element. This attribute enables you to place <textarea> elements anywhere within a document, not just as descendants of form elements.

hidden: Option<bool>

An enumerated attribute indicating that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. The browser won't render such elements. This attribute must not be used to hide content that could legitimately be shown.

id: Option<&'life str>

Defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).

inert: Option<&'life str>

A boolean value that makes the browser disregard user input events for the element. Useful when click events are present.

inputmode: Option<&'life str>

Provides a hint to browsers about the type of virtual keyboard configuration to use when editing this element or its contents. Used primarily on <input> elements, but is usable on any element while in contenteditable mode.

is: Option<&'life str>

Allows you to specify that a standard HTML element should behave like a registered custom built-in element (see Using custom elements for more details).

maxlength: Option<&'life str>

The maximum number of characters (UTF-16 code units) that the user can enter. If this value isn't specified, the user can enter an unlimited number of characters.

minlength: Option<&'life str>

The minimum number of characters (UTF-16 code units) required that the user should enter.

name: Option<&'life str>

The name of the control.

placeholder: Option<&'life str>

A hint to the user of what can be entered in the control. Carriage returns or line-feeds within the placeholder text must be treated as line breaks when rendering the hint.

Note: Placeholders should only be used to show an example of the type of data that should be entered into a form; they are not a substitute for a proper <label> element tied to the input. See <input> labels for a full explanation.

readonly: Option<bool>

This Boolean attribute indicates that the user cannot modify the value of the control. Unlike the disabled attribute, the readonly attribute does not prevent the user from clicking or selecting in the control. The value of a read-only control is still submitted with the form.

required: Option<bool>

This attribute specifies that the user must fill in a value before submitting a form.

rows: Option<&'life str>

The number of visible text lines for the control. If it is specified, it must be a positive integer. If it is not specified, the default value is 2.

spellcheck: Option<&'life str>

Specifies whether the <textarea> is subject to spell checking by the underlying browser/OS. The value can be:

• true: Indicates that the element needs to have its spelling and grammar checked.
• default : Indicates that the element is to act according to a default behavior, possibly based on the parent element's own spellcheck value.
• false : Indicates that the element should not be spell checked.

wrap: Option<&'life str>

<p>Indicates how the control should wrap the value for form submission. Possible values are:</p>
<ul>
  <li><code>hard</code>: The browser automatically inserts line breaks (CR+LF) so that each line is no longer than the width of the control; the <a href="#cols"><code>cols</code></a> attribute must be specified for this to take effect</li>
  <li><code>soft</code>: The browser ensures that all line breaks in the entered value are a <code>CR+LF</code> pair, but no additional line breaks are added to the value.</li>
  <li><code>off</code> <abbr title="Non-standard. Check cross-browser support before using." class="icon icon-nonstandard">
<span class="visually-hidden">Non-standard</span>

: Like soft but changes appearance to white-space: pre so line segments exceeding cols are not wrapped and the <textarea> becomes horizontally scrollable.

If this attribute is not specified, soft is its default value.

extra: BTreeMap<&'life str, &'life str>

The extra attributes of the element. This is a map of attribute names to their values. The attribute names are in lowercase.
