Step 2: Now we will add the HTML drop-down list.

<div>
<select class="chzn-select" style="width: 350px;" tabindex="2" data-placeholder="Choose a Country...">
<option value=""></option>
<option value="United States">United States</option>
<option value="United Kingdom">United Kingdom</option>
<option value="Afghanistan">Afghanistan</option>
<option value="Zambia">Zambia</option>
<option value="Zimbabwe">Zimbabwe</option>
</select></div>

We have created a simple HTMl option list and added class chzn-select.

  $(document).ready(function(){
 $("select").chosen({allow_single_deselect:true});
