Hello,

We have one document type Product. Under product we have different categories.

Product:
=>Furniture
=>Chair
=>Tables
=> Carpets etc.
=>Carpet1
=>Carpet2

Now we have another document type as Booking Event.

Event:
Event1
Event2

Now we want when somebody is creating new event e.g. Event3. Whatever categories we have under product should be added under that newly created Event.

So final look,

Event1
Event2
Event3
=>Furniture
=>Chair
=>Tables
=> Carpets etc.
=>Carpet1
=>Carpet2

How we can achieve this? Any help will be appreciated.

Thanks
