You don't need to include it as a hidden field, just remember that
your callback function has to return the entire array. It's going
straight into the database from there. So make sure you pull any
options you want to preserve out of the DB and put them in the new
array. Might be simplest to just pull out the existing array then
update it with the incoming options instead.
