There is a grouptabpanel contain several menu and sub-menu items with grid inside. For now, there is one and only way to access them all through

Let say there is a Configuration menu and Language sub-menu. The problem is, how to define a proper url, to get access directly to Language sub-menu. For example, the URL should be like

Here is the initial code:

xtype: 'grouptabpanel',
            tabWidth: 200,
            activeGroup: 6,
            items: [
                expanded: true,
                items: [
                    xtype: 'portal',
                    title: 'Configuration',
                    tabTip: 'Dashboard tabtip',
                    autoHeight: true,
                    title: 'Language',
                    itemId: 'language',
                    url : 'main/test2',
                    layout: 'fit',
                    iconCls: 'x-icon-tickets',
                    tabTip: 'Language tabtip',
                    style: 'padding: 10px;',
How to achieve that? Any advices or solutions really really appreciated.

Thanks in advance.
