Inserting a New list to a existing List at specified Level

Hello Guys,
I want to merge this 2 List like this.

ANy Help?

Hi @sounakbanerjee.hetc

Use List.AddItemToEnd node with lacing longest.

Dang @Kulkul beat me to it.

and is more correct, lacing set to longest:

List.combine with a list.join as combinator would also work! :slight_smile:
With that method you could also change some thing a little bit if you need to and you can extend it to have 3 lists as input.
