title: put an element always on bottom while sorting
body: <p>I have a list of items (div, for instance) with an integer attribute that helps me sorting that list (ascending and descending); I want some items always at the bottom not matter the sort criteria, is there a way to put a value on this integer attribute to get this (separately, I put -9999 while desc order, and 999999 in asc order, but I need only one value).</p>
