If your options are objects, you must provide the `isOptionEqualToValue` prop to ensure correct selection and highlighting. By default, it uses strict equality to compare options with the current value.

:::warning
If your options have duplicate labels, you must extract a unique key with the `getOptionKey` prop.

{ label: 'The Godfather', id: 2 },
];

return <Autocomplete options={options} getOptionKey={(option) => option.id} />;
```
