},
constructor : function(config) {
    this.initConfig(config);

    return this;
},    
collapsible: true,
autoScroll:true,

});

you can use it as follow.

handler : function() {                      
        i = i + 1;
        var group = new My.Group({
            title : 'Group' + i.toString(),
            id : '_group-' + i.toString()
        });
        // console.log(this);
        // console.log(group);
        Ext.getCmp('panelid').insert(i, group);
        Ext.getCmp('panelid').doLayout();
    }
