This function allows you to rearrange the structure of the menu's within the application. The left most panel allows you to select the required menu and the middle panel shows which options (including other menus) which are currently attached to it. You can move options (Modules) from the assigned (centre) panel to the unassigned (right) panel as required. The menu described as root has a special significance as this is the bottom level menu from which are other menus are branched. Menu changes will only be visible to users once they logout and login again. You should also note that only menu's to which a user has Permissions to access will be displayed.
