Definition and Usage

The disabled attribute is a boolean attribute.

The disabled attribute specifies that a group of form elements (a fieldset) should be disabled.

A disabled fieldset is unusable and un-clickable.

The disabled attribute can be set to allow users to use the input fields only when certain conditions are met (such as selecting a checkbox, etc.). Then, JavaScript can be used to remove the disabled value, making the fieldset usable.

Differences between HTML 4.01 and HTML5

The disabled attribute is a new attribute of the <fieldset> tag in HTML5.

Differences between HTML and XHTML
