Hi there .. yes documentation is not totally updated .. however the tutorials project provides n example in the file projects/tutorials/menu.php file.. it shoudl look like this
if you copy this concept to your project folder menu.php file and change the relevant $dropdown_menu to reflect the relevant url.
Also you can change the static menu, which in this example shows a welcome message ... you might want to change this to addyour owntext ..
also... if you do the above then you lose access to all report links but you might want to easily accessall reports in admin/design mode so set $admin_menu
$admin_menu = array (
array ( "language" => "en_gb", "report" => ".*\.xml", "title" => "<AUTO>" )
Let me know if that helps or not!!
