I mean:
Themes > Menu > Add Menu > Add Category and there the search field for categories.
Could you please modify it thus it works?
I also tried this code:
add_action( 'pre_get_posts', 'myFilter1', 10, 2 );
function myFilter1( $q ) {
if(isset($_POST['action']) && $_POST['action']=="menu-quick-search" && isset($_POST['menu-settings-column-nonce'])){
if( is_a($q->query_vars['walker'], 'Walker_Nav_Menu_Checklist') ){
$q->query_vars['posts_per_page'] = 15000;
}
}
return $q;
}
without any effect.
