title: Form elements with digestive-functors
body: <p>Digestive-functors-blaze creates html like <code>&lt;input type="text" id="foo" name="foo" /&gt;&lt;label for="foo"&gt;Bar&lt;/label&gt;</code>, but I didn't find any standard way to for example add <code>&lt;br /&gt;</code> to the end.</p>
  
  <p>I came up with this:</p>
  
  <pre><code>br :: (Monad m) =&gt; HappstackForm m H.Html BlazeFormHtml ()
  br = Common.label $ \_ -&gt; do
    createFormHtml $ \cfg -&gt; do
      H.br
  </code></pre>
  
  <p>I can append it with <code>&lt;++</code> which does what I expect it to, but I wonder whether this is the intended way?</p>
  
  <p>Also how would this extend with for example fieldsets.</p>
