The snippet below shows how the component can be used
// import component
import React, { Component } from 'react';
import { View } from 'react-native';
import MultiSelect from 'react-native-multiple-select';
const items = [{
id: '92iijs7yta',
name: 'Ondo'
}, {
id: 'a0s0a8ssbsd',
name: 'Ogun'
}, {
id: '16hbajsabsd',

];
class MultiSelectExample extends Component {
state = {
selectedItems : []
};
onSelectedItemsChange = selectedItems => {
this.setState({ selectedItems });
};
render() {
const { selectedItems } = this.state;
return (
<View style={{ flex: 1 }}>
<MultiSelect
hideTags
items={items}
uniqueKey="id"
ref={(component) => { this.multiSelect = component }}
onSelectedItemsChange={this.onSelectedItemsChange}
selectedItems={selectedItems}
selectText="Pick Items"
searchInputPlaceholderText="Search Items..."
onChangeInput={ (text)=> console.log(text)}
altFontFamily="ProximaNova-Light"
tagRemoveIconColor="#CCC"
tagBorderColor="#CCC"
tagTextColor="#CCC"
selectedItemTextColor="#CCC"
selectedItemIconColor="#CCC"
itemTextColor="#000"
displayKey="name"
searchInputStyle={{ color: '#CCC' }}
submitButtonColor="#CCC"
submitButtonText="Submit"
/>
<View>
{this.multiSelect.getSelectedItemsExt(selectedItems)}
</View>
</View>
);
}
}The component takes 3 compulsory props - items, uniqueKey and onSelectedItemsChange. Other props are optional. The table below explains more.
| Prop | Required | Purpose |
|---|---|---|
| altFontFamily | No | (String) Font family for searchInputPlaceholderText |

See this issue for more info. |
| filterMethod | No | (String) Defaults to "partial". options: ["partial", "full"] Choose the logic on how the system filters items based on searchTerm. partial: checks all individual words and if at least one word matches will include that item. full: checks to ensure the item contains the full substring of searchterm in order minus any leading or trailing spaces. |

-
Tokenized selected items can be displayed in any other part of the view by adding a
refto theMultiSelectcomponent like soref={(component) => { this.multiSelect = component }}. Then add this to any part of the screen you want the tokens to show up:this.multiSelect.getSelectedItemsExt(selectedItems). TheselectedItemsargument passed into the above mentioned method is the sameselectedItemspassed as the main component selected items prop. (See example above). -
If users shouldn't be able to select any of the items in the dropdown list, set a
disabledkey to true in the item. Such item will be rendered in gray and won't be clickable. -
When using the
singleprop,selectedItemsshould still be passed in as an array of selected items keys. Also, when an item is selected in the single mode, the selected item is returned as an array of string. -
The
itemsprops must be passed as an array of objects with a compulsorynamekey present in each object as the name key is used to display the items in the options component. -
filterMethod partial example: searchTerm = "University of New" will return "University of New York", "University of New Orleans", "The University of New York" as well as "University of Columbia" and "New England Tech" due to partial matches.
-
filterMethod full example: searchTerm = "University of New" will return" University of New York", "University of New Orleans", "The University of New York" because all three contain the substring "University of New"
To use, add ref to MultiSelect component in parent component, then call method against reference. i.e.
<MultiSelect
ref={c => this._multiSelect = c}
...
/>
clearSelectedCategories = () => {
this._multiSelect._removeAllItems();
