Select

The HTML   element presents a menu of options. The options within the menu are represented by  elements, which can be grouped by   elements.

Attributes

 * - Specifies that a form control should have input focus when the page loads, unless the user overrides it, for example by typing in a different control. Only one form element in a document can have this attribute, which is a Boolean. (HTML5)
 * - 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 ; if there is no containing element with the disabled attribute set, then the control is enabled.
 * - The  element that this element is associated with (its "form owner"). The value of this attribute must be an ID of a   element in the same document. If this attribute is not specified, this element must be a descendant of a   element. This attribute enables you to place   elements anywhere within a document, not just as descendants of their   elements. (HTML5)
 * - 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.
 * - Specifies the name of the control.
 * - If the control is presented as a scrolled list box, this attribute represents the number of rows in the list that should be visible at one time. Browsers are not required to present  elements as a scrolled list box.
