Yii2 onchange action plus value of selected option

So I currently have the below code which on change I want to redirect the user to the action using the value selected.

For example I have articles/posts linked to only one category no sub sub categories. I want the dropdown menu to redirect the user to category view.

So my url will be something like /article/index?category=1

     <?php $form = ActiveForm::begin(['id' => 'category-form', 'action' => '/advanced/article/Category',]); ?>

 <?= $form->field($model, 'category')->dropDownList($model->categoryList,[

'prompt'=>'Select Category to view',


]) ?>

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

Currently learning yii2 so any guidance on how to accomplish this would be great.

Any ideas guides or tutorial that can point me in the right direction?

Does it need to be a GET request rather than POST?

Or should it be a redirect of some kind onchange so the URL would be localhost:/advanced/article/action?parameter=id <— value of dropdown selection.
