title: jQuery's Flexigrid show/hide columns feature in the header
body: <p>Here is my Flexigrid:</p>
  
  <pre><code>$("#grUser").flexigrid({
      url: 'someJSON.php'
      , dataType: 'json'
      , colModel : 
      [
          {display: '', name : 'Index', width :100, align: 'left'}
          , {display: '', name : 'Value', width : 100, align: 'left'}
      ]
      , title: 'Details'
      , width: 350
      , height: 200
      , singleSelect: true 
  });
  </code></pre>
  
  <p>The show/hide columns feature in the header is really cool option, but <strong>I want to specify on which column to be available</strong>, and I am having trouble finding a good documentation about what are my options in specifying the colModel. Here</p>
  
  <pre><code>{display: '', name : 'Index', width :100, align: 'left'}
  </code></pre>
  
  <p>What else can we put in the definition of a column?</p>
  
  <p>Additionally - what is your documentation source for Flexigrid?</p>
