## Modifiers

```ts
import { restrictToParent, snapToGrid } from '@vue-dnd-kit/core';

makeSortableList(list, { items, modifiers: [restrictToParent] });
makeDragArea(board, { modifiers: [snapToGrid({ x: 24, y: 24, smooth: true })] });
```

A modifier takes the drag's offset and returns a new one. They run in order: the provider's
`modifiers`, a drag area's, the draggable's own (or its list's), then the area's bounds
(`restrictToArea`), and the `axis` lock last. See [Axes, bounds and grids](https://zizigy.github.io/docs/guides/constraints).

## Collision detection

```ts
import { closestCorners } from '@vue-dnd-kit/core';
```

```vue
<DnDProvider :collision="closestCorners" />
```

The provider's `collision` picks the target; the best candidate comes first.
