Hi @kuruka6

Use “+” node or use code block “list[0] + list[1]”.  
There many examples on forum please use forum seach. Here is one [Combine 2 Lists of Strings with a separator](https://forum.dynamobim.com/t/combine-2-lists-of-strings-with-a-separator/4116/8?u=kulkul)

List.transpose might also help here. Watch the lacing and levels.
