Please update your easyui library to the latest version. Or download the updated menu plugin from http://www.jeasyui.com/easyui/plugins/jquery.menu.js and include it to your page.

Here is the example http://jsfiddle.net/h5Hf8/ that works fine.

Update version 1.34 to 1.35. This question is ok. thank you!

You set a wrong 'height' value style(height:70%). Please try the code instead.

Code:

<div  style='width:150px;height:200px;overflow:auto'>
...
</div>

excuse me, this problem still exist.

    <div id="mm" class="easyui-menu" >
        <div id="menudetail">
        <span data-options ='iconCls:icon-add'>插入</span><div  style='width:150px;height:70%;overflow:auto'>
         <div><b>TEST</b></div>
          ......
         <div><b>TEST</b></div>
   </div>



A lot of blank  when set 'overflow:auto' for div,

Code:

                $('#tt').tabs('add', {
                    title: 'apiname',
                    content: 'content',
                    closable: false,
                    selected:true,
