Hi,
I have checked the example for customization (Version 10 & 12) and I saw thta there is a process CustomLoadSubMenuItems where we can configure own entries at the sidemenu, but I was not able to configure there something with structure like this:

So main menu item "Instruction" has 3 children "New Instruction", "Search" & "Instruction Configuration". Also menu item "Instruction Configuration" has 2 children "Distribution List" & "Distribution Template"
Is there a possibility to do something like this without changing the original portal-project?
Thank you in advance
Katrin
