title: I want a date select box with blank values selected by default
body: <p>I used the following <code>date_select</code> helpers but none of them shows a date select box with blank values selected by default. With all the following code, I get the select box but with the current date selected. I'm on Rails 2.3.2</p>
  <pre><code>&lt;%= f.date_select :featured_at, :default =&gt; {:day =&gt; nil, :month =&gt; nil, :year =&gt; nil} %&gt;
  &lt;%#= date_select(&quot;post&quot;, &quot;featured_at&quot;, :prompt =&gt; { :day =&gt; 'Select day', :month =&gt; 'Select month', :year =&gt; 'Select year' }) %&gt;
  &lt;%#= date_select(&quot;post&quot;, &quot;featured_at&quot;, :default =&gt; { :day =&gt; nil }) %&gt;
  &lt;%#= f.date_select :featured_at, :include_blank =&gt; true, :order =&gt; [:day, :month, :year] %&gt;
  </code></pre>
