How to make items persist in an item

[superhighlevel]

First, thank you for making a great Inventory system.
I'm trying to make an indie game that has an inventory system like Escape From Tarkov(EFT). In this game, a backpack item can hold other items. I try to save ItemRef, if save the item here but the other function does not work as intended. I tried to work around it by making an Inventory Node and linking to that Item but this will makes save the file so much harder

There were some discussions about nested inventories in the past and there's an open issue for that, but unfortunately, there's still no "official" support for that. Hopefully it will be possible to do once version 3.0 is out (still work-in-progress). Until then, you can play around with extending InventoryItem, adding an Inventory member and making custom UI controls, but I haven't tried anything similar and I can't tell you how to implement it exactly nor if it will work ☹️

Thank you for your response, I find a workaround for this case. It uses version 3.0, and makes a lot of modifications to make it work
Basically, I saved every item in Inventory, index, position, and item prototype,... and loaded/Added Items with that info when needed.
