title: CSS/Javascript: dynamic multiple columns
body: <p>I need to build a dynamic multiple columns view for the content of my website (I'm using drupal as CMS, if can be useful info), with the following features</p>
  
  <p>1) the columns width is fixed (OK)</p>
  
  <p>2) the columns number depends on the window width (OK)</p>
  
  <p>3) the elements has not fixed height (important, not fixed yet)</p>
  
  <p>4) the content should be possibly vertically distributed (no idea how to do this, since I use css attribute float:left)</p>
  
  <p>See this screenshot to better understand: <a href="http://dl.dropbox.com/u/72686/grid.png" rel="nofollow noreferrer">http://dl.dropbox.com/u/72686/grid.png</a></p>
  
  <p>thanks</p>
