Any chance you'd have a quick fix on this?
This precise issue was mentioned by Johan Ronsse: http://www.slideshare.net/Wolfr/designing-better-user-interfaces starting from page 31.
This particular issue seems to create confusion for some end-users. I had dropkick on a mandatory form field and users were complaining that they couldn't "type in" the value so they would just give up. Had to get rid of dropkick and go back to native dropdown fields.
