Hello,

I am trying to turn a list into multiple lists based on the level.

Can someone tell me a node that can do It?

Wondering If doing It like this would be a good Idea, since In this project I have 14 lists, but In another could be more or less..

Which turns the scipt semi automatic.

A list of list is actually multiple lists (nested). What you need from that point forward is to structure your data and steps in such a way that the result is correct with however many nested lists you get.

Check [Lists in Primer](https://primer2.dynamobim.org/5_essential_nodes_and_concepts/5-4_designing-with-lists) to see that structure happening.
