Definition and Usage

The Disabled attribute is a boolean attribute.

If present, it specifies that an option should be disabled.

Disabled options are not available and cannot be clicked.

You can set the Disabled property to prevent the user from selecting the option until other conditions are met (such as checking a checkbox, etc.). Then, JavaScript is needed to remove the disabled value and make the option selectable.
