title: Knockout options conditional css
body: <p>I have an observable array of objects </p>
  
  <pre><code>question = {
          ownerUserName: item.id,
          text: item.text,
          dataType: item.dataType,
          personalized: item.personalized,
          status: item.status,
          actionUserName: item.actionUserName
      }
  </code></pre>
  
  <p>And a select with options from this array:</p>
  
  <pre><code>&lt;select id="questId" style="width: 425px" data-bind="options: questionList, optionsText: 'text'"&gt;
  </code></pre>
  
  <p>How with the help of knockout can I make so that if question.personalized == "Y" color of the text of this question would be green?</p>
