Textarea component is a styled
textarea element and is exposed for
cases where you need to implement a custom interface.
There are three options for the
size of the Textarea input,
"medium" is the default.
"subtle". For use in data-dense interfaces you can apply a
"none" to hide
the "chrome" of the input until the user interacts with it, on hover or focus.
value is initialized with
useState, so that the text area starts
off with some text in it.
