title: Rails Form: f.select for multiple options
body: <p>For my user form, I have a hobbies drop-down menu and I want to be able to select more than one option (one user may have skiing, reading, and chess as hobbies).</p>
  
  <p>Of course, doing this is very <a href="https://stackoverflow.com/questions/4864513/ruby-on-rails-multiple-selection-in-f-select">easy</a>! </p>
  
  <p>However, none of the available options seem to work for me...</p>
  
  <p>Here's my code:</p>
  
  <pre><code>&lt;%= f.select :hobbies, [['Chess','chess'],
                          ['Movies','movies'],
                          ['Videogames','videogames'],
                          ['Skiing', 'skiing'],
                          ['Reading','reading']],
                          {:multiple =&gt; true} %&gt;
  </code></pre>
  
  <p>However, when I look at my form, I don't think this is working. It makes the drop-down menu....but how do I select multiple entries? I try ctr + click but it doesn't do anything....what am I missing? It keeps just selecting one value only...</p>
