• It is better to use standard <!--. . .--> comment rather than this tag.
• Because the comment element is not supported by all browsers, commented text
done in this fashion will appear in other browsers.
<datalist> (List of Prefill Data)

type="list" . These listed items would be considered the quick choices for the field, not
a limitation of what can be entered, which would be the functionality of a select menu.
