Описание

Тег <select> позволяет создать элемент интерфейса в виде раскрывающегося списка, а также список с одним или множественным выбором, как показано далее. Конечный вид зависит от использования атрибута size тега <select>, который устанавливает высоту списка. Ширина списка определяется самым широким текстом, указанным в теге <option>, а также может изменяться с помощью стилей. Каждый пункт создается с помощью тега <option>, который должен быть вложен в контейнер <select>. Если планируется отправлять данные списка на сервер, то требуется поместить элемент <select> внутрь формы. Это также необходимо, когда к данным списка идет обращение через скрипты.
