body: <p>I am attemping to add Select2 library to my project, but I am failing miserably:</p>

  <p>My code looks like this:</p>
  
  <pre><code>&lt;head&gt;

  <p>In the body:</p>
  
  <pre><code>&lt;form&gt;
    &lt;input type="hidden" name="page" value="products"/&gt;
    &lt;div class="form-group"&gt;
      &lt;label for="exampleInputEmail1"&gt;Include&lt;/label&gt;
      &lt;select class="form-control select2" name="inc" multiple&gt;
        &lt;option&gt;Chicken&lt;/option&gt;
        &lt;option&gt;Ready Meals&lt;/option&gt;
        &lt;option&gt;Rice&lt;/option&gt;
      &lt;/select&gt;
    &lt;/div&gt;
    &lt;div class="form-group"&gt;
      &lt;label for="exampleInputPassword1"&gt;Exclude&lt;/label&gt;
      &lt;select class="form-control select2" name="exc" multiple&gt;
        &lt;option&gt;Chicken&lt;/option&gt;
        &lt;option&gt;Ready Meals&lt;/option&gt;
        &lt;option&gt;Rice&lt;/option&gt;
      &lt;/select&gt;
    &lt;/div&gt;
    &lt;script type="text/javascript"&gt;
      $(".select2").select2({ multiple: true});
    &lt;/script&gt;
    &lt;div class="checkbox"&gt;
      &lt;label&gt;
        &lt;input type="checkbox"&gt; Check me out
      &lt;/label&gt;
    &lt;/div&gt;
    &lt;button type="submit" class="btn btn-default"&gt;Submit&lt;/button&gt;
   &lt;/form&gt;
