<?php use yii\helpers\Html;

$this->registerJs(

//~ 'jQuery.noConflict();


'$("document").ready(function($){


$("body").on("click", ".seat", function(e) {


	  var url = $(this).attr("href");


	  $("#seatModal").find(".modal-body").load( url );


	  $("#seatModal").modal({ backdrop: "static", keyboard: true });


	  e.preventDefault();


	  return false;


	});


	});'

);

[size=2]<?php [/size]

	[size=2]echo Html::a(Yii::t('app', ' {modelClass}', [[/size]


			'modelClass' => 'Select City',


			]), ['site/city'], ['class' => 'btn btn-link seat']


			[size=2]); [/size]

?>

<div class="modal fade " id="seatModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

  <div class="modal-dialog">


    <div class="modal-content">


      <div class="modal-header">


        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>


        <h4 class="modal-title" id="myModalLabel">Seat Selection</h4>


      </div>


      <div class="modal-body">


        


      </div>


      <div class="modal-footer">


        


        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>


      </div>


    </div>


  </div>


</div>

Controller

public function actionCity()


{


	//~ $this->layout= "null";


	$model = new Locations();


     return $this->renderAjax('select_city', [


            'model' => $model,


        ]);


}

and this is the view that i want to popup

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


<div class="col-md-6">


<?php 


$items = ArrayHelper::map(Locations::find()->all(), 'id', 'name');


echo $form->field($model, 'name')->dropDownList($items)


?>    


</div>


<div class="form-group">








<?php echo Html::a(Yii::t('app', ' {modelClass}', [


						'modelClass' => 'OK',


					]), ['site/choose'], ['class' => 'btn btn-success	']


					


					); ?> 





</div>





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