To be clear, you are proposing that I create a new component that generates a
div with css that makes it appear to be a TextArea, then when I determine
(determination based upon the user/data) that I want a readonly TextArea, I
replace the real TextArea with a FakeTextArea prior to rendering?
Before I attempt this myself, has anyone created a div based TextArea
component, that can be made available to me?
