title: Selecting every first option of multiple select elements
body: <p>I have an html file with multiple select elements. What is needed is that the text of every first option of a select element is changed with jQuery. The answer given is <code>$('select').children().first().html('changed!');</code>. But this does not change <em>all</em> the first option texts, only the first one.</p>
  
  <p>What is the proper way to go about this?</p>
