title: how to specify label for select in simpleform rails
body: <pre><code>&lt;%= f.association :opportunity_status, :label =&gt; "Status", :input_html =&gt; {} %&gt;
  &lt;%= f.select :source_type, options_for_select(["lead","vteam"],["lead"]) %&gt;
  </code></pre>
  
  <p>On first line every thing is OK. On second line if I attach label the way I did in first line it show an error.</p>
