Extract elements of a list with indexes

Hi All, I hope you can help me with the list management. I have to create a list composed of elements extracted from another list. The new list must have the same structure of the first. I tried it this way …? Thank you and good day to all.

Hi Daniele,

Try “Flatten” node after “List.AllIndicesOf”.

Seems to work in ver 1.0

Thank you guys!

Vikram is just what I need!

I try now to install version 1.0

Thanks again!
