New onBeforeCapture responder #1588
<DragDropContext /> | onBeforeCapture is called after we know a drag will start, but before any dimensions have been collected from the DOM. It is an opportunity to add or remove <Draggable /> and <Droppable /> components, or modify element sizes.
⚠️ Warning: this is pretty powerful and it can be used to do great things, as well as terrible things.
For more details, check out our responders guide
In the following example, I am adding a trash bin (<Droppable />) in onBeforeCapture with some items (<Draggable />) in it to show off the kind of thing you can do ♻️
