Creating linkedin like Inbox Menu in Ext JS 4

[naveedanjum]

I found if i could create LinkedIn.com like Inbox[4] menu in Ext JS. Along with Invitation Person Picture, basic details and accept / reject option.

toolbar.add
        (
            '-',
            {
                text:'Inbox',
                iconCls:'inbox-icon',
                menu:
                {
                    items: [
                                {
                                    xtype:'label',
                                    html:'<img src="images/brComms.jpg" />'
                                }    
                           ]
                }
                
            }        
        );

I had stared writing basic code in Ext JS 4 but dont have idea how to achieve this. An idea will be appreciated.
