Comment (by johnmadox):

 Hello,
 I am kinda new to wordpress and am building an online store by the help of
 different videos.
 Can you please explain where and how to add this code?
 I would really appreciate if anyone could help me out.
 Thanks

 > I found a somewhat simpler (more targeted) solution to disable
 pagination in these meta boxes, by placing a filter on the
 {{{nav_menu_meta_box_object}}} hook:

 > <?php
 >   add_filter( 'nav_menu_meta_box_object', array( $this,
 'disable_pagination_in_menu_meta_box' ) );
 >
 >   function disable_pagination_in_menu_meta_box($obj) {
 >     $obj->_default_query = array(
 >       'posts_per_page' => -1
 >     );
 >     return $obj;
 >   }
 > ?>
 > }}}
 >
 > Please be advised that this uses the private-looking `_default_query`,
 so your mileage may vary, but it worked very well for me.
