Yii2 Scroll Pager
Yii2 Scroll Pager (Y2SP) turns your regular paginated page into an
infinite scrolling page using AJAX.
Y2SP works with a Pagination object which specifies the totally number of pages and the current page number.
Pager is build with help of JQuery Infinite Ajax Scroll plugin.
Requirements
- Yii 2.0
- PHP 5.4
Installation
The preferred way to install this extension is through Composer.
Either run
php composer.phar require kop/yii2-scroll-pager "dev-master"
or add
"kop/yii2-scroll-pager": "dev-master"

Just pass the ScrollPager class name to the ListView pager configuration.
Make sure that items in your list have some classes that can be used as JavaScript selectors.
