The <select> HTML element represents a control that provides a menu of options.

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>

A string providing a hint for a user agent's autocomplete feature. See The HTML autocomplete attribute for a complete list of values and details on how to use autocomplete.

autofocus: Option<bool>

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

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().

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 with the disabled attribute set, then 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 to associate the <select> with (its form owner). The value of this attribute must be the id of a <form> in the same document. (If this attribute is not set, the <select> is associated with its ancestor <form> element, if any.)

This attribute lets you associate <select> elements to <form>s anywhere in the document, not just inside a <form>. It can also override an ancestor <form> element.

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).

multiple: Option<bool>

This Boolean attribute indicates that multiple options can be selected in the list. If it is not specified, then only one option can be selected at a time. When multiple is specified, most browsers will show a scrolling list box instead of a single line dropdown.

name: Option<&'life str>

This attribute is used to specify the name of the control.

required: Option<bool>

A Boolean attribute indicating that an option with a non-empty string value must be selected.

size: Option<&'life str>

If the control is presented as a scrolling list box (e.g. when multiple is specified), this attribute represents the number of rows in the list that should be visible at one time. Browsers are not required to present a select element as a scrolled list box. The default value is 0.

Note: According to the HTML specification, the default value for size should be 1; however, in practice, this has been found to break some websites, and no other browser currently does that, so Mozilla has opted to continue to return 0 for the time being with Firefox.

Trait Implementations

impl<'life> Clone for Select<'life>

fn clone(&self) -> Select<'life>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'life> Debug for Select<'life>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'life> Default for Select<'life>

fn default() -> Select<'life>

Returns the “default value” for a type.

impl<'life> Ord for Select<'life>

fn cmp(&self, other: &Select<'life>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'life> PartialEq<Select<'life>> for Select<'life>

fn eq(&self, other: &Select<'life>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'life> PartialOrd<Select<'life>> for Select<'life>

fn partial_cmp(&self, other: &Select<'life>) -> Option<Ordering>

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

fn ge(&self, other: &Rhs) -> bool
