Dropdown add new value when clicking on 'other' option


(Nishitadoval) #1

Hello all,
I am new to yii and I was trying to create a dropdown list with an ‘other’ option at last and when i click on it, a popup occurs of a text field and then i enter a value there and it gets added to the list,so that it shows the updated list.
How can i do this?

This is my form
<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\helpers\ArrayHelper;
use yii\web\JsExpression;

/* @var $this yii\web\View /
/
@var $model app\models\Department /
/
@var $form yii\widgets\ActiveForm */
?>

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($model, 'deptname')->textInput(['maxlength' => true]) ?>

 <?= $form->field($model, 'deptlocation')->dropDownList(
        ArrayHelper::map(\app\models\Location::find()->all(), 'loc', 'loc'), // Flat array ('id'=>'label')
        ['prompt' => 'Select',]) 
    ?>

<div class="form-group">
    <?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?>
</div>

<?php ActiveForm::end(); ?>

Thank you
