Business Attributes - Custom

[efrainclg95]

Dear expert friends, always hoping that you are well, I come to you to ask a topic related to Business Attributes.
It turns out that I try to put together the following scheme:

-Product
  -Product 01
      -Sub Product 01
      -Sub Product 02
  -Product 02
      -Sub Product 01
      -Sub Product 02

I have tried to do it, but without success, I just managed to put together this scheme:

-Product
  -Product 01
  -Product 02

I do not know if there is a way to add the Sub Products as in the initial scheme or some way of filtering.
I have tried to go through the documentation, but did not find anything related.
Once again I appreciate your time and your reach in this scenario that I have to solve.

Stay tuned.
Thanks.

display-type --> enum-tree (for this type)

is the solution
