Thanks for responding.
Unfortunately - I get this error when I apply your example;
Using IE10:
SCRIPT438: Object doesn't support property or method 'call'
jquery.easyui.min.js, line 2987 character 1
And the same in Chrome
Uncaught TypeError: undefined is not a function jquery.easyui.min.js:2987
I am using EasyUI 1.4
This is my layout (modified from EasyUI demo)
<body id="cc" class="easyui-layout">
<div id="header" data-options="region:'north',border:false" style="height:40px;background:#4682B4;padding:10px; color:#ffffff;"><h2>Sample</h2></div>
<div data-options="region:'west',split:true, collapsed:false, onCollapse:'onCollapse'" id="navigator" title="Navigator" style="width:200px;padding:0;"></div>
<div id="workspace" data-options="region:'center',title:'...'"></div>
<div id="debug" data-options="region:'south',split:true, collapsed:false, iconCls:'icon-ok'" title="Debug" style="height:100px;padding:0;">
</body>
