在Accordion样式的Viewport菜单中，怎么添加超链接啊？

var viewport = new Ext.Viewport({
        layout:'border',
        items:[{
            region:'west',
            id:'west-panel',
            title:'Menu',
            split:true,
            width: 150,
            minSize: 175,
            maxSize: 400,
            collapsible: true,
            margins:'35 0 5 5',
            cmargins:'35 5 5 5',
            layout:'Accordion',
            layoutConfig:{
//titleCollapse: true,
//activeOnTop: true,
                animate:true
            },
            items: [{
                // html: Ext.example.shortBogusMarkup,
                title:'Summary',
                autoScroll:true,
                border:false,
                iconCls:'nav'
            },{
                title:'Services',
                // html: Ext.example.shortBogusMarkup,
                border:false,
                autoScroll:true,
                iconCls:'nav'
            }]

如上面的代码，想让“Summary”和"Services"在点击时，超链到另一个页面该怎么做啊？？

没有人知道么？ 是不是不好实现呢？
