No, you haven't bothered to explain why these items need *both* (a) to
look like text and yet (b) function is input fields. The code you have
seems to accomplish what it is you want superficially, yet you asked
your question, so I'm trying to figure out what your underlying goal is
that might lead one to look for a different approach.
