如何在jquery中默认折叠所有手风琴

我只需要一些关于手风琴的帮助。我想要的是如何在加载页面时默认折叠所有手风琴？我的目标是始终显示所有手风琴内容。我该怎么做？以下是我在代码中所做的操作。

  <script>
    $(function() {
      $( "#accordion" ).accordion({
         collapsible: true, 
         autoHeight: false, 
         active: false 
      });
    });
  </script>
<div id="accordion">
              <h3>MASTER LIST</h3>
                <div>
                    <?php
                        echo anchor('category_controller/homepage','Categories');
                        echo "<br />";
                        echo anchor('item_controller/index','Items');
                        echo "<br />";
                        echo anchor('supplier_controller/index','Suppliers');
                        echo "<br />";
