Hi Aquatis, It is indeed possible to add a side menu with different nodes.  What you have to do is create a new menu section for the "Menu (vertical)" plugin to use.  Simply go to Organizer > Menu Navigation and then in the level 2 section of that click on "All menu sections". There will be a drop down that says "Advanced" click on that and choose "Create a menu section". Then enter the pages you want in that menu area. Once complete go to the properties of the vertical menu where there will be an option to choose the menu section. Simply select your new section and it will display. Hope this can get you started.  Simon.
