readonly

Sets the read-only state of the textarea. A read-only field cannot be modified (however, a user can tab to it, highlight it, and copy the text from it).

The readonly attribute can be set to keep a user from changing the value until some other conditions have been met (like selecting a checkbox, etc.). Then, a JavaScript can remove the readonly value, and make the textarea field editable.

Default value

False - the textarea is editable.

Valid values

True, False, or any valid XPath expression that returns a boolean value.
