(EVALSYS-426) UI Improvement - improve 'vertical' display for large numbers of multiple choice options

Hi Harriet,

At least based on the mockup, I don't see any accessibility issues  
with this approach. You're using standard radio buttons, so they're in  
the tab order and fully navigable with the keyboard.

One thing I'm a bit confused by: how can you make multiple selections  
if you're using radio buttons? I'm assuming this is for multiple  
choice not multiple selection, right?

 From a usability perspective, it would be much better to group the  
radio buttons into smaller, more manageable chunks. But I'm assuming  
that you're not able to do that in this case, perhaps because these  
forms will be user-authored?

Hope this helps,

Colin
