Multiple grids on one page

Every Yii2 widget has so much encapsulated in it that using multiple GridView widgets is a simple activity that involves making few changes.

The only parameters indeed that are not customizable with the DataProvider model class are pageParam and sortParam, which define the current page index and the parameters used to order a grid.

Suppose, for example, that we have two GridViews filled with two different data providers, $firstDataProvider and $secondDataProvider.

In the controller, we will set the pageParam and sortParam parameters of each DataProvider:

$firstDataProvider->pagination->pageParam = 'first-dp-page';
$firstDataProvider->sort->sortParam = 'first-dp-sort';

$secondDataProvider->pagination->pageParam = 'second-dp-page';
$secondDataProvider->sort->sortParam = 'second-dp-sort';

If we miss these definitions when changing a page or sorting a column, this action will also affect the other GridView in the same page because we have not distinguished...
