Definition and Usage

The disabled attribute is a boolean attribute.

When present, it specifies that an option-group should be disabled.

A disabled option-group is unusable and un-clickable.

The disabled attribute can be set to keep a user from selecting the option-group until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript is required to remove the disabled value, and make the option-group selectable.

Differences Between HTML 4.01 and HTML5

None.
