title: Can a div be shown outside of browser window?
body: <p>I've noticed that the HTML SELECT dropdown can be drawn outside of the browser window.
  For example look at it:
  <a href="http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select" rel="nofollow">http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select</a></p>
  
  <p>Make your browser's window height very small, and you'll notice that even if it's small the html select dropdown goes beyond the edges of the browser's window.</p>
  
  <p>Now I'm making my own dropdown using absolutely positioned divs with a high z-index, but they seem to be cut off by the browser window edges if the window is very small. Is there a way to do this or make it act like an html select? </p>
