# Ordering

```php
->sortAttribute('sort')
```

With a sort attribute, people reorder cards by hand.

* The board sends only the new neighbours. The server writes a single row with a position halfway between them.
* When positions get too close, or legacy rows have none, that column is renumbered once in the same transaction.
* Float, decimal and integer columns all work, so an existing `order_column` from spatie/eloquent-sortable can be reused.

::: tip
Index `(status, sort)` for large boards.

Without a sort attribute, cards follow your query's order and only change column.
