Adds a page size selector to grid views and list views.
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist nkovacs/yii2-pagesizer "*"
or add
"nkovacs/yii2-pagesizer": "*"
to the require section of your composer.json file.
Once the extension is installed, replace \yii\grid\GridView with \nkovacs\pagesizer\GridView and \yii\widgets\ListView with \nkovacs\pagesizer\ListView.
You can use {pagesizer} inside the $layout property to customize the page sizer widget's placement, and the $pageSizer property to customize
the page sizer widget.
