AMP components used in this example (the AMP story component):

<!-- This is the AMP component that enable functionality used on this page (AMP-bind, AMP-list and AMP-mustache). -->
<script async custom-element="amp-bind" src="https://cdn.ampproject.org/v0/amp-bind-0.1.js"></script>
<script async custom-element="amp-list" src="https://cdn.ampproject.org/v0/amp-list-0.1.js"></script>
<script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.1.js"></script>

All of the preceding code blocks should be put in the document head. The following code blocks should reside in the document body.
Using AMP-bind to select which request to send to the server

<p>
Sort by
 <select on="change:AMP.setState({
              products: {
              sortChoiceValue: event.value,
              listSrc: 'request.php?sort='+event.value+'&_=RANDOM'
              }
              })" name="country" id="country" required >
      <option value="priceAsc">Price Lowest to Highest</option>
      <option value="priceDesc">Price Highest to Lowest</option>
    <option value="ratingAsc">Rating Lowest to Highest</option>
    <option value="ratingDesc">Rating Highest to Lowest</option>
  </select>
</p>

This combination of AMP-list and AMP-mustace is used to retrieve the products in a specified order.

<amp-list width="auto"
  height="600"
  layout="fixed-height"
  src="request.php"
  [src]="products.listSrc">
  <template type="amp-mustache">
    <div class="url-entry">
    <table width="100%">
      <tr valign="top">
      <td width="35%">
          <amp-img src="images/{{image}}" height="200" width="100"></amp-img>
      </td>
      <td>
            <h3>{{name}}</h3>
      <p><br>
    ${{price}}<br>
    {{rating}}</p>
      </td>
    </tr>
    </table>
    </div>
  </template>
</amp-list>
