    ]); 
    $dataList=ArrayHelper::map($companies, 'id', 'name');
    echo Typeahead::widget([
    'model' => $companySearched, 
    'name'=>'coSearch',

    'pluginOptions' => ['highlight'=>true],
    'dataset' => [
        [

This can be solved with the help of a hidden field.I use autocomplete here

<?php
use yii\web\JsExpression;
use yii\jui\AutoComplete;

$data = Company::find()
->select(['name as value', 'name as  label','c_id as id'])
->asArray()
->all();

echo AutoComplete::widget([
'name' => 'Company',
'id' => 'ddd',
'clientOptions' => [
'source' => $data,
'autoFill'=>true,
'minLength'=>'4',
'select' => new JsExpression("function( event, ui ) {
    $('#model-company').val(ui.item.id);
 }")],
 ]);
 ?>

 <?= Html::activeHiddenInput($model, 'company')?>

Hope this help!
