title: Active / Inactive icons in bootstrap 3.1.1
body: <p>I am trying to add a sorting column with active / inactive sort on a column.My idea is to either gray-out the inactive columns or highlight the active column in a grid . I tried sth like this</p>
  
  <pre><code>&lt;button type="button" class="btn btn-default btn-sm"&gt;
      Order By Status &lt;span class="glyphicon glyphicon-sort"&gt;&lt;/span&gt;
  &lt;/button&gt;
  </code></pre>
