So I stumbled across the coolest thing ever! Okay. Maybe not the coolest thing ever but it's pretty slick and I have to say it's going to make some of the UI issues you've been experiencing go away.
It's the Chosen jQuery library (which you can find here: https://harvesthq.github.io/chosen/). Essentially it does magic things to select boxes on forms and makes 'em WAY easier to deal with.
I'm currently playing around with it on the good ol' dev server and I have to say, I'm pleased with the results. It even works pretty well on a mobile device. Now... I guess that is to say that it doesn't modify the interface that iOS throws on top of select fields and that's actually brilliant.
Oh, I think you're going to like the results, my friends.
