title: how to layout bootstrap form with multi column?
body: <p>what I want is like this:</p>
  
  <p><strong>5 element:</strong>  label , textfield , read-only-label, auto-fill-textfield, icon-btn</p>
  
  <p>and some spacer between them just as the img show.</p>
  
  <p><img src="https://i.stack.imgur.com/vyLpR.png" alt="what I want"></p>
  
  <p>but I found it's really hard to handle this.</p>
  
  <p>could anyone show me an example jsfiddle, thanks.</p>
