实施多个组合框仅需一个下拉按钮

Question

Using the code here : http://jqueryui.com/autocomplete/#combobox But replacing id with a class results in almost the desired functionality... except there is only drop down button for all combox box's. How to get a drop down button for each combobox ?

<div class="ui-widget" style="display: inline-block;" >
  <select id="tag01" class="comboBox">
    <option value="">Select one...</option>
      <c:forEach items="${allTags}" var="tag">
        <option value="${tag.title}">${tag.title}</option>
      </c:forEach>
   </select>
</div>
<div class="ui-widget" style="display: inline-block;" >
  <select id="tag02" class="comboBox">
    <option value="">Select one...</option>
    <c:forEach items="${allTags}" var="tag">
      <option value="${tag.title}">${tag.title}</option>
    </c:forEach>
  </select>
</div>

and then calling comboxbox like so :

 $("#tag01").combobox();
 $("#tag02").combobox();

or

 $(".comboBox").combobox();

results in only one drop down button. Only if I remove display inline block from style of divs do I get multiple buttons, but then the combox boxs are on multiple lines - I do not want this.

The drop down button is absolutely positioned, which means it does not impact the normal flow of the page. When you add the second combo box, the combination with position: relative in the container element leads to a box stacked on top of the button. Leaving some space on the right of the .ui-widget elements solves the problem.

For example,

<div class="ui-widget" style="display: inline-block; margin-right:40px">
  <select id="tag01" class="comboBox">
    ...
   </select>
</div>
