I have a example model like that but I don’t know how to make it recursive because I may have n amount of features or cases. for example I can’t create case under child feature or I can’t create feature under child feature. I can’t use my methods under child feature’s child feature. but I can use them in my parent.

https://paste.mod.gg/dtnvlxwutido/0 this is my model structure.

https://paste.mod.gg/bokpwbismsii/0 this is my controller.

https://paste.mod.gg/yoripjuhljra/0// and this is my service.

I tried to make recursive but didn’t manage to do it successfully.
