You can try using a compaction strategy.

ty for the response! it does work to a certain extent to what I was expecting, It could be part of the elk's algorithm but as I added more nodes in this example, node n9 is pushed to the bottom but alignment TOP did not work.
For nodes 10, 11, 12, they are not evenly aligned at the top either (picture is something I was expecting)

If i add edgerouting POLYLINE, it is similar to what I need, but the compaction strategy does not work with edge routing is this correct?

Here is another good example of n7 and n9 being pushed down, i think it is because the graph is trying to reduce the gap horizontally? and minimize empty space. My goal essentially would just be each child to be in its own tree regardless if it needs to push the sibling nodes out creating a big horizontal gap
Example

If this is the case, I suggest introducing hierarchy to achieve this (and make the hierarchical node invisible).

i see, seems like sub flow is the only way to achieve this, i would need to apply child to a child for every node. Not sure if I want to go that route.

Thanks for the help!
