title: moving input field below the button
body: <p>I have a question how to set this up.
  Here is the example: <a href="http://jsfiddle.net/VBS4E/25/" rel="nofollow">http://jsfiddle.net/VBS4E/25/</a></p>
  
  <p>What's a good way to move the input field right below the button? Like this:</p>
  
  <pre><code> ________   __________   __________
  |  Btn#1 |  |  Btn#2 |  |   Btn#3  |
   ________    _________   __________
  </code></pre>
  
  <p>When click on Btn#2,</p>
  
  <pre><code> ________   __________   __________
  |  Btn#1 |  |  Btn#2 |  |   Btn#3  |
   ________    _________   __________
                   _____________
           Label: |_____________|
  </code></pre>
