@williamdes I'm try this sample

import React, { Component } from 'react';
import { View } from 'react-native';
import MultiSelect from 'react-native-multiple-select';

class MultiSelectExample extends Component {

  this.state = {
    selectedItems = [];
  };

  this.items = [{
    id: '92iijs7yta',
    name: 'Ondo',
  }, {
    id: 'a0s0a8ssbsd',
    name: 'Ogun',
  }, {
    id: '16hbajsabsd',
    name: 'Calabar',
  }, {
    id: 'nahs75a5sg',
    name: 'Lagos',
  }, {
    id: '667atsas',
    name: 'Maiduguri',
  }, {
    id: 'hsyasajs',
    name: 'Anambra',
  }, {
    id: 'djsjudksjd',
    name: 'Benue',
  }, {
    id: 'sdhyaysdj',
    name: 'Kaduna',
  }, {
    id: 'suudydjsjd',
    name: 'Abuja',
  }];

  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"
