Okay, so first of all, I'm calling a dropdown wheel because I don't know if there is a name for it, so this is what I believe is the logical name for it.
I've come to see this around in phones and such for a while. The thing is, I am no CSS expert at all(I'm a newby in that sense), and when I found libraries that could do this they were convoluted jquery libraries that, I don't know about you, but just looking made me not want to touch it.
So the question is, how would one most elegantly implement this with a dropdown (or a set of unspecified elements where you know that they can at fit in the same size - like in a regular dropdown list)?
