Creating menu with group folder

Hi !

I already have my addon menu working but i want to create a sub menu (group) like the one with the folder icon in SBO main menu. Ex:

Addon Menu (in main menu pop-up)

Utilities (sub menu with a folder design besides it)

Add

Remove

Report

All my sub menus are individually listed under Addon Menu ... what would be the code to group them under utilies under Addon Menu ????

Thanks..
