Grouping List Options

The optgroup element is used to group options in a drop-down list, with the aim of making the list easier to navigate. The functionality essentially splits large numbers of <option> items into small sections. Note that the label attribute is required, and will be rendered as the first item in the section. The user cannot select the label as a choice.
