Duplicate GET param in forms

[gephaest]

I have form (in widget view):

<?= Html::beginForm('', 'GET', ['id' => 'header-search']); ?>
<?= Html::textInput('search', ''); ?>
<?= Html::submitButton(Yii::t('ui', 'Search')); ?>
<?= Html::endForm(); ?>

If i click on Search button few times GET parameter duplicating:

With ActiveForm same situation

You have to configure the form action explicitly, it is default to the current request URL so it includes all the params already that were sent by the previous form submit. Set it to be the plain URL without params explicitly.
