Content Grid provides a lot of options and one of the best one is of filters to filter posts. The filters to provide much better user experience automatically scroll the page to the filtered posts. This is useful specially in case of Mobile Devices where view port is quite restricted.
If you want to disable the auto-scrolling then please add the following filter to the theme’s functions.php file.
<?php // PowerPack Content Grid prevent scroll animation on filtering add_filter( 'pp_cg_scroll_to_grid_on_filter', '__return_false' );
