a custom element combined with JavaScript.

• This element is currently in extremely raw form and without implementations its
usage should be considered speculative.

This nonstandard Internet Explorer element treats enclosed text as comments. This element
should not be used.

data="URL" (6)
id="unique alphanumeric identifier" (4)

Element-Specific Attribute
data
This attribute references a URL that contains the comment information.
Example
<comment>
This is not the proper way to form
comments!!!
</comment>
Compatibility
No standards support
Internet Explorer 4, 5, 5.5, 6
Notes
• 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)
This HTML5 element contains
option
elements that populate an
input
element with
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.
