## Usage

##### Install the package
```
npm i react-native-dropdown-autocomplete
```

##### Wrap the page you want to have autocomplete on with ```withKeyboardAwareScrollView```:

```javascript
import React, {Component} from "react";
import {StyleSheet, View, SafeAreaView} from "react-native";
import {Ionicons} from "@expo/vector-icons";
import shortid from "shortid";
import {Autocomplete, withKeyboardAwareScrollView} from "react-native-dropdown-autocomplete";

class HomeScreen extends Component {
  handleSelectItem(item, index) {
    const {onDropdownClose} = this.props;
    onDropdownClose();
    console.log(item);
  }

  render() {
    const autocompletes = [...Array(10).keys()];

    const apiUrl = "https://5b927fd14c818e001456e967.mockapi.io/branches";

    const {scrollToInput, onDropdownClose, onDropdownShow} = this.props;

    return (
      <View style={styles.autocompletesContainer}>
        <SafeAreaView>
          {autocompletes.map(() => (
            <Autocomplete
              key={shortid.generate()}
              style={styles.input}
              scrollToInput={ev => scrollToInput(ev)}
              handleSelectItem={(item, id) => this.handleSelectItem(item, id)}
              onDropdownClose={() => onDropdownClose()}
              onDropdownShow={() => onDropdownShow()}
              renderIcon={() => (
                <Ionicons name="ios-add-circle-outline" size={20} color="#c7c6c1" style={styles.plus} />
              )}
              fetchDataUrl={apiUrl}
              minimumCharactersCount={2}
              highlightText
              valueExtractor={item => item.name}
              rightContent
              rightTextExtractor={item => item.properties}
            />
          ))}
        </SafeAreaView>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  autocompletesContainer: {
    paddingTop: 0,
    zIndex: 1,
    width: "100%",
    paddingHorizontal: 8,
  },
  input: {maxHeight: 40},
  inputContainer: {
    display: "flex",
    flexShrink: 0,
    flexGrow: 0,
    flexDirection: "row",
    flexWrap: "wrap",
    alignItems: "center",
    borderBottomWidth: 1,
    borderColor: "#c7c6c1",
    paddingVertical: 13,
    paddingLeft: 12,
    paddingRight: "5%",
    width: "100%",
    justifyContent: "flex-start",
  },
  container: {
    flex: 1,
    backgroundColor: "#ffffff",
  },
  plus: {
    position: "absolute",
    left: 15,
    top: 10,
  },
});

export default withKeyboardAwareScrollView(HomeScreen);
```

## Usage without data-driven content
You can also pass fixed array of items to the Autocomplete
```javascript
const data = [
  "Apples",
  "Broccoli",
  "Chicken",
  "Duck",
  "Eggs",
  "Fish",
  "Granola",
  "Hash Browns",
];
```

Change valueExtractor and pass the data to Autocomplete without fetchDataUrl
```javascript
<Autocomplete data={data} valueExtractor={item => item} />
```

  While developing our react-native application I found out that there's no autocomplete library available which can satisfy a need for > 1 autocomplete on a page. Styles were overlapping and due to position: "absolute" we weren't able to actually trigger TouchableOpacity on an element from the list on android device. We used a library which provides dropdown with auto-adjusting position using measureInWindow on a ref, we tweaked it a bit and with autocomplete input and time-slicing implementation we managed to get what we need. Still we can't interact with TextInput component while dropdown is opened but this is the best result we got using React Native Modal.
