Description

**Is your feature request related to a problem? Please describe.**
I have been using native paper for different projects and I came across a problem several times where I needed an autocomplete component, I tried 2 packages but I would love to have a component from the native paper so that my UI remains consistent

**Describe the solution you'd like**
I implemented an autocomplete component with the use of TextInput + Menu component from native paper
```ts
interface Props> {
theme?: AppTheme;
value: {
origValue: string | undefined;
};
label: string;
data: T[];
displayKey: keyof T;
containerStyle?: StyleProp;
onChange: (text: string) => void;
leadingIcon?: IconSource;
trailingIcon?: IconSource;
textInputstyle?: StyleProp;
menuStyle?: StyleProp;
textInputRight?: ReactNode;
textInputLeft?: ReactNode;
}

const Autocomplete = >({
theme = lightTheme,
value: propValue,
label,
data,
displayKey,
containerStyle = {},
onChange: originOnChange,
textInputstyle = {},
leadingIcon = "",
trailingIcon = "",
menuStyle = {},
textInputRight = null,
textInputLeft = null,
}: Props) => {
const [value, setValue] = useState(propValue.origValue);
const [menuVisible, setMenuVisible] = useState(false);

return (

{
if (value || value?.length === 0) {
setMenuVisible(true);
}
}}
outlineStyle={
menuVisible
? {
borderBottomRightRadius: 0,
borderBottomLeftRadius: 0,
}
: {}
}
onBlur={() => setMenuVisible(false)}
label={label}
{...(textInputRight ? { right: textInputRight } : {})}
{...(textInputLeft ? { left: textInputLeft } : {})}
style={textInputstyle}
onChangeText={(text) => {
originOnChange(text);
setMenuVisible(true);
setValue(text);
}}
value={value}
/>
{menuVisible && (

{data.length === 0 && (


No result found


)}
{data.map((item, index) => (
{
const selectedValue = String(item[displayKey]);
console.log(selectedValue);

setValue(selectedValue);
setMenuVisible(false);
originOnChange(selectedValue);
}}
title={String(item[displayKey])}
/>
))}

)}

);
};

```

**Describe alternatives you've considered**
I have tried two alternatives:
react-native-autocomplete-dropdown and react-native-autocomplete-input
I dropped those packages out of fear since they were backed only by one contributor.

**Additional context**
N/A

Research direction

Start by reviewing the existing TextInput and Menu component APIs, then compare the proposed TypeScript component with the alternatives named in the issue. Clarify the intended autocomplete behavior, public API, styling, and interaction states before implementation. Done means the component fits the library's existing patterns and has agreed coverage for its expected behavior.
