Can column-count be split into 2 checkbox areas in a div?

I have a list of checkboxes in a div and some jquery which splits the enabled checkboxes and places them in an area above the disabled checkboxes (this is nothing to do with 'ticked' checkboxes). For each area, I want to display 2 columns in a vertical flow so the checkboxes show alphabetically top down. The layout of the labels should be as follows:

Austria        Germany
Denmark        Hungary
Estonia        Latvia
_______________________

Bulgaria       Ireland
Croatia        Malta

The country list needs to be flexible, so simply rearranging the labels in HTML won't work. I've naively tried using column-count and column-width, but this messes up the enabled and disabled checkbox areas. Ideally a CSS solution would be great but not sure its possible. Any help greatly appreciated. Fiddle: http://ift.tt/2AYK1cc
