title: Rails store key value for a select input
body: <p>I have in my .html.erb:</p>
  
  <pre><code> &lt;label for="form_marital_status"&gt;Marital Status:&lt;/label&gt;
   &lt;%= select("form", "marital_status", marital_status_options, {}, { }) %&gt;
  </code></pre>
  
  <p>Where <code>marital_status_options</code> is defined in my helper as:</p>
  
  <pre><code> def marital_status_options
        %w[Select Single Married Common-Law/Partner Divorced Widowed]
   end
  </code></pre>
  
  <p>Is there a way I can define <code>marital_status_options</code> to have a key value pairing for use in the select?</p>
