I looked at this repository, but then when I ran the demo, I noticed it just renders the selection rectangle without allowing me to select elements inside of a rectangle.
Question is, is there a way to allow users to select multiple elements with drag-select in React-DnD? I looked at the documentation and there's nothing about this.
This is not possible with react-dnd by itself. Something like react-dnd-multiple-selection (https://github.com/znwang25/react-dnd-multiple-selection) might be closer to what you're looking for.
