optionelement

The option element represents a single option in a list of choices for a select element or a datalist. In a native select, options appear as items in a drop-down; in a datalist, options act as suggested values for the associated input.

Attributes and content: The value attribute defines the option’s submission value. If value is omitted, the option’s text content is used as its value. The label attribute can provide a separate label from the displayed text. The boolean attributes selected and defaultSelected indicate whether the option is selected by default; in a single-select, only one option can be selected at a time. The disabled attribute prevents selection and disables the option in the list.

Behavior with forms: When a form is submitted, the value of the selected option is sent under the name of the select element. For a multiple select, all selected options are submitted. In a datalist, selecting an option fills the input’s value but does not submit an independent value.

Accessibility and parsing: Options participate in keyboard navigation and are announced by assistive technologies in order. Disabled options are skipped and visually indicated. The option element must be a child of a select or a datalist to participate in native controls.

Example: Within a select, an option can be represented as <option value="1">One</option>. When multiple selections are allowed, multiple options can have the selected attribute.
