About 3 or more levels on tree

Hi, I have not seen this question. I have 3 levels to import with CSV to Hikashop, and I'm doing this:
parent_category: For the main level
categories: for the second level

But some products has 3 levels, I have tried do other column, but says that it's twice. Please could you say me what I have to write for the 3th level column? Thank you!!

Hi,

For these products, you can do like that:
parent_category: For the second level
categories: for the third level
Just make sure that you already have the categories of the first and second level already created in your backend before the import.

Hi Nicolas! Thank you for your answer. It's ok for the 2nd and 3rd level, but where I write the firts level in the CSV? For example if the main categorie is BOOKS, the 1st level is Fiction and 2nd level is Best seller (it's only a sample). Thank you!! The parent_category should be fiction, categories Best Seller, but where goes books? Thank you again!!

Hi! Sorry! I understand, I should create it before. Thank you!!
