By default WordPress includes a very basic pagination system though what if you wanted more? Using the plugin WP-PageNavi you can customize the pagination system from layout, styling and so on.
If you run a big blog, you should implement page navigation so that your users can easily navigate across the blog. WP-PageNavi is a WordPress plugin with which you can easily add page navigation.
As you can see in the above video, WP-PageNavi plugin doesn’t support few third party themes. However, the plugin works with the default WordPress theme.
WP-PageNavi enables you to display page navigation in drop down menu. However, this functionality was not worked when I tested the plugin.
