不重新加载页面的Yii2搜索表单

我有一个选项卡布局的页面。我为gridview构建了一个搜索表单。但每次我使用搜索时，它都会重新加载页面并将我带回第一个选项卡。我怎样才能解决这个问题

这是我的密码：

<?php $form = ActiveForm::begin([
     'options' => ['data-pjax' => true ],
    'action' => ['index'],
    'method' => 'get',
    ]); ?>

    Approve month: <input type="string" name="approvemonth"><br><br>
    Team: <input type="string" name="team"><br><br>
    Difficulty: <input type="string" name="difficulty">

    <div class="form-group">
    <?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?>
    <?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?>
    </div>

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


    <?php echo GridView::widget([
            'dataProvider' => $dataProvider15,
            'filterModel' => true,  
            'pjax'=>true,
            'panel' => [
                'type' => GridView::TYPE_PRIMARY,
                'heading' => '<h3 class="panel-title"><i class="glyphicon glyphicon-user"></i>Avg total time by modeler without handover</h3>',
            ],
            'columns' => [
                [
                'attribute'=>'approvemonth', 
                'filter' => Html::input('string', 'approvemonth'),
                [
                    'attribute' =>'team',
                    'filter' => Html::input('string', 'team'),
                    // 'group' => true,
                ],
                [
                    'attribute' =>'difficulty',
                    'filter' => Html::input('string', 'difficulty'),
                    // 'group' => true,
                ],
                [
                    'attribute' =>'Total',
                    'format'=>['decimal',2]
                ],
                [
                    'attribute' =>'Avg',
                    'format'=>['decimal',2]
                ],
            ]
        ]); 
        ?>

困难：
这是因为您没有将表单包装在

<?php Pjax::begin()?>
<?php Pjax::end()?>

我可以看到您如何在上面的代码中使用Pjax，添加更新的代码非常感谢：）我的问题是我在表单之后使用Pjax:：end（），而不是覆盖整个表。非常感谢。
<?php \yii\widgets\Pjax::begin();?>
<?php $form = ActiveForm::begin([
    'options' => ['data-pjax' => true],
    'action' => ['index'],
    'method' => 'get',

    Team: <input type="string" name="team"><br><br>
    Difficulty: <input type="string" name="difficulty">

    <div class="form-group">
    <?=Html::submitButton('Search', ['class' => 'btn btn-primary'])?>
    <?=Html::resetButton('Reset', ['class' => 'btn btn-default'])?>
    </div>

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