I don't know how to specify item-key

[nickear]

draggable has an item-key property. My list is a dynamic string array, so I don't know how to specify this property. Will it cause any problems if I omit it?

I had a similar problem, I have used :item-key="(item: string) => item" as I do not have an object, I also have an array of strings.
