How to put custom profile field into postbit

[MikeF]

There was a guy who wrote a whole custom product for custom profile fields in the postbit for 3.8. I doubt he wants to do it again for 4. Anyway, the great thing about this mod was that you could put a whole bunch of custom fields in a dropdown. I forget if it was using AJAX for the dropdown or Javascript, but eitherway, it worked great. So you could have, for example, a "car" icon or a "computer" icon, and then have those custom profile fields display in a dropdown menu.

Now we are back in the stone age until someone comes up with something as great as that add-on.
