Dnd 2.0 Migration

Replace the global touch shim

createTouchDragShim() and TouchDragOptions were removed. Enable touch on each sortable scope instead.

// Before
createTouchDragShim();
const scope = createSortableScope();

// After
const scope = createSortableScope({ touch: true });

Touch input now only recognizes sortable items registered to its scope. Its default preview is an inert outline; touch.preview may return an element that Dnd clones for the transient preview.

Move cross-list persistence to the scope

Cross-container moves no longer call onReorder once for each affected list. Persist the transaction from scope.onMove, which receives the moved item and both final orders. Local keyboard and single-list drag reorders continue to call each sortable's onReorder.

const scope = createSortableScope({
  onMove: ({ itemId, sourceIds, targetIds }) => {
    persistMove(itemId, sourceIds, targetIds);
  },
});
