A drop-down list with one disabled option:
The disabled attribute is a boolean attribute.
When present, it specifies that an option should be disabled.
A disabled option is unusable and un-clickable.
The disabled attribute can be set to keep a user from selecting the option 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 selectable.
The numbers in the table specify the first browser version that fully supports the attribute.

In XHTML, attribute minimization is forbidden, and the disabled attribute must be defined as <option disabled="disabled">.
