Options structure

By default, the component accepts the following options structures:

interface AutocompleteOption {
  label: string;
}
// or
type AutocompleteOption = string;

for instance:

const options = [
  { title: 'Forrest Gump', year: 1994 },
  { title: 'Inception', year: 2010 },
];
// or
const options = ['Forrest Gump', 'Inception'];

However, you can use different structures by providing a getOptionLabel prop.

Controlled states

The component has two states that can be controlled:

  1. the "value" state with the value/onChange props combination. This state represents the value selected by the user, for instance when pressing Enter.

  2. the "input value" state with the inputValue/onInputChange props combination. This state represents the value displayed in the textbox.

These two states are isolated, and should be controlled independently.

value: ""
inputValue: "

If you control the value, make sure it's referentially stable between renders. In other words, the reference to the value shouldn't change if the value itself doesn't change.

// ⚠️ BAD
return <Autocomplete multiple value={allValues.filter((v) => v.selected)} />;

// 👍 GOOD
const selectedValues = React.useMemo(
  () => allValues.filter((v) => v.selected),
  [allValues],
);
return <Autocomplete multiple value={selectedValues} />;

In the first example, allValues.filter is called and returns a new array every render. The fix includes memoizing the value, so it changes only when needed.

Grouped

You can group the options with the groupBy prop. If you do so, make sure that the options are also sorted with the same dimension that they are grouped by, otherwise, you will notice duplicate headers.
