I need to present a list to a user and allow him/her to break it up into 5 priority zones of severity. The zones will then have different background colors or some other indicator. ie 100+ = Very high, 85+ = High etc... It will not always be uniform across all categories

 

I had the following possible solution:  Using KnockoutJS set up 6 lists with only those containing records visible.  It would start with all items in an "Unselected" list.  The user would select items, press a button and those items would go into the appropriate empty list thus showing them. There would be a cancel selections button.

 

Does anyone have a better suggestion?  It would be a lot cooler if there was just one list and the user could make 5 zones out of it, but I don't know how to make the selectable widget do that.
