pager

This option specifies whether the view listing files from an archive uses a pager at the bottom. If the pager is enabled ('enable' parameter is true) then you can also adjust the number of rows listed per page ('page_size') and the number of page numbers displayed in the navigator ('pager_size').

/*
 * enable/disable pager and set its size
 */
'pager' => array(
    'page_size'  => 40,
    'pager_size' => 14,
    'enabled'    => true
),
