You have to create parent menus and then child menus.

In v7 you have to create two parent menus and then child menus to which you can bind actions in your xml file.

<menuitem name="Parent Root A" id="menu_parent_root_a"/>
<menuitem name="Parent A" id="menu_parent_a" parent="menu_parent_root_a"/>
<menuitem name="Child Action Menu" id="menu_child_action" parent="menu_parent_a" action="your_action_id"/>

You may find more examples in OpenERP addons. Addons are our best friend in OpenERP.

Hope this will help you.
