I have a three-level list that I’m trying to sort. I have managed to use the Sort by Key to sort two levels of the list but I’m missing how I can sort all three levels. I found the Clockwork SortListOfLists and that does work. I’m wondering if there’s a way to do it with built-in nodes. ![Capture2](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/a/0aaa3cc80fcf21d8f6b62399764c53410f2b8a41.png) Thanks again!

@Thom_Krejci Concatenate the values and use it as a key to sort. ![Capture](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/6/86d7f0b38a8fe6d76bff6258c3d5c8b876b9e756.png) ---

Greetings! Thank you for that quick response: That worked perfectly! I would not have thought of combining them and then splitting them again. Thank you again for giving me new insight on lists. -Thom K.
