  <p>my code:</p>
  <pre><code>    $(document).ready(function(){
            $('.input1').iconpicker(&quot;.input1&quot;)
            .append( &quot;&lt;p&gt;Test&lt;/p&gt;&quot; );
            $('#inputid2').iconpicker(&quot;#inputid2&quot;);
            $('.input3').iconpicker(&quot;.input3&quot;);
          });
  
   &lt;input type=&quot;text&quot; class=&quot;input1 input&quot;/&gt;
        &lt;br/&gt;&lt;br/&gt;
        &lt;h4&gt;Value == Amazon&lt;/h4&gt;
        &lt;input type=&quot;text&quot; class=&quot;input&quot; id=&quot;inputid2&quot; value=&quot;fa-amazon&quot;/&gt;
        &lt;br/&gt;&lt;br/&gt;
        &lt;h4&gt;Just for fun&lt;/h4&gt;
