Hi, i am a beginner on dynamo and would like to know how i can use a sorted list to sort another one… ! ![dyna](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/d/3d0d6c3c18d6bfddb229be3270b865382f3d4dc3.jpeg) Thanks per advance !! ---

List.SortByKey Sorting a list by a key… And please use screenshots not potato-phone-pictures… It physically hurts the eyes ---

Alternatively you can (instead of grouping and sorting separately (it works either way)) use the Orchid node… ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/a/6a7edf6e32087b77041d26d761f96e17944f2e03.png) But as you’re working with lists-within-lists-within-lists… you NEED to use list levels a lot. ---

Thanks for the test but even in yours, the result at the end is not the one expected: elements in your watch node are in the wrong order , the right result should have been: element1,element2,element3,e4 and ,e5,e6,e7… instead of e1, e3, e2, e4 & e7,e6,e5… Sorry 😕 ---

> [@rbrision](#): > > in the wrong order No… They are exactly as expected… the order is sorted from assumed to be unsorted in the beginning… and elements taking the places corresponding to the sorting of the corrected order… So the final order is exactly as one would expect… ---

Thank you for your advices guyzz. But my goal is not achieved, maybe i havent very well explained what i aim for. ![Capture77](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/b/eb144a66f404aaba9d263f4cb9acd8b4c741abd4.jpeg) My Goal is to obtain the list 1 in the order of the list 2. Maybe because as a grasshopper user my logic is different but i don’t understand why in every solution you purpose i never get what i want … !!! ---

Do you want to do something like this ? If it is only sorting your rooms another way… > [@Sorting Curve List A by Curve List B](https://forum.dynamobim.com/t/sorting-curve-list-a-by-curve-list-b/25774/5): > > Edit : Same method as Alban, really [Capture] ---

@mellouze Thanks for your comment, but as you can see the number of the rooms are now completely diffrent from the initial list. It has taken only one item of the right “Level” and repeated it …Nice try but this is still not the expected result ! 🙂 ![dyna2](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/5/4597922f2ead55f8d5ac7b4ef27875b9e20c06e9.jpeg) ---

Use **List.UniqueItems** on your keys and use **List.AllIndexOf** instead. It should work if you tweak a little bit your graph. Try things on your own and experiment with Dynamo. Only that why you’ll progress 😉 ---

Have you tried SortByFunction? I know it is in 2.0, not sure about earlier Dynamo versions. ![sortbyfunction](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/b/0b77a73984edb82f76a4c52cd17af536d5753126.png) ---

Hi @kennyb6 You could also use @ListLevel to avoid **List.Sort** node: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/8/38665a623d5b474544a72f8d8e0529ab5f58175b.png) ---
