How can add array inside another array? using useFieldArray()?

[PetrusBorges]

basically i have a array of houses e inside of each a need do push a array of rooms, how can i be able to create any rooms i need for eatch houses i created in form?

this exemple that i show dont works for houses.${index}.rooms

fieldNote for houses works well, but fieldRooms to name: houses.${houseIndex}.rooms dont works

from the docs:

Name of the field array. Note: Do not support dynamic name.

you can’t nest useFieldArray like this, if you want nested arrays of fields, you have to give them dynamic name when registering / using <Controller /> like this:

houses.${houseIndex}.rooms.${roomIndex}.name etc
