Hey @Darren thanks for the reply. Yes, this resizing issue happens across different browsers/computers (I tested with Brave and Chrome, and Windows/Mac).
Either way, I managed to get it working with the Stack component, even having these issues.
I have other thing that I need to tackle regarding a drag and drop component (the reorderable list does not fit to my needs).
I found this post in the forum: Custom Drag-and-Drop Component for Retool 🎉
Seems like someone was able to achieve the drag-n-drop with a custom component. Is there any approach for me to have something similar to that?
