How can I exclude page(s) from nav menu? I found some examples where field called "**exclude**" was added to args and reportedly it worked. Maybe it's just deprecated. I have version 4.1.5. 

My current code is: 

```
$avia_theme_location = 'avia';
$avia_menu_class = $avia_theme_location . '-menu';
$args = array(
    'theme_location' => $avia_theme_location,
    'menu_id' => $avia_menu_class,
    'exclude' => '29, 30, 31, 32',
    'menu_class' => 'menu av-main-nav',
    'container_class' => $avia_menu_class.' av-main-nav-wrap'.$icon_beside,
    'fallback_cb' => 'avia_fallback_menu',
    'walker' => new avia_responsive_mega_menu()
);

wp_nav_menu($args);

```

Where 29,30,31 and 32 are pages IDs what I want to exclude and they are correct.
