i'm currently using fixed position with some calculation to overcome this issue

It looks like the drag line just expands downward from the center between the items by the height of the line. If possible, you should be able to just move the line up with CSS by the fixed amount that the line has in height. For example, in the sample style, the line has a height of 4px, and is moved back up by css by 2px to recenter it.

I have the same issue essentially. my nodes don't have consistent height. and it seems to plot the spaces for them based on the hard coded height @--rct-item-height

this makes the drag and drop unstable very frustrating as I've put a lot of time setting this up for my use case and added the dynamically displayed elements as a last action I figured would be fast. but I was mistaken. my bad for not testing all functionality before moving forward. this is such a great library though!

Hi Austin, yes, RCT doesn't currently support elements of varying heights at the moment. Thank you very much for your contribution in the linked PR, I left some comments on your proposed changes.
