Hey HN! I just released Puck 0.18 with a new drag-and-drop engine for CSS grid and flexbox support. You can now use Puck to create a page builder that behaves like a design tool, but embedded within your own app and using your own React components. To use it, just add `display: flex` (or grid, etc) to your DropZone and Puck will gracefully handle drag-and-drop across all dimensions. Shout out to the dnd-kit maintainer Claudéric for the collaboration and support (if you’re reading this, I just sponsored you on GitHub!) and as always, a huge thanks to my wonderful community for all the testing…
