Excellent tutorial, exactly what I searched for. With several tweaks to the if statement I got desired results.

Thanks!

 'Movies',
 'post_status' => 'publish',
 'paged' => $home_paged
);
query_posts($arguments);
?>

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); //beginning of loop

 if('nav_menu_item' !== get_post_type()) : // ADD THIS LINE  Exclude navigation menu items.

// rest of your loop code 

and at the end of the loop,

<?php endif; //ADD THIS LINE

(plus of course add closing php tag but I think that was causing my code to get stripped out, so I omitted it here).

At the beginning of the loop:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); //beginning of loop

 if('nav_menu_item' !== get_post_type()) : // ADD THIS LINE  Exclude navigation menu items.

// rest of your loop code

At the end of the loop:

The following is the only solution I found that allowed me to use the code Justin provided here without either a) wiping out navigation menu items, or b) including navigation menu items but then having the menu items show up as though they were posts (which, let me tell you, looks extremely stupid)…neither of which is at all an acceptable solution.

Steps:
1) Follow Justin’s directions to include the custom post types on your homepage.
2) To get the navigation menu items to reappear:
As some others have suggested, add ‘nav_menu_item’ to your array of custom post types in the code Justin has provided.
3) To prevent navigation menu items from also appearing within the loop as if they are posts:
Just inside of the loop, add an if statement to exclude the nav_menu_item post type.

For example, at the beginning of the loop:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); //beginning of loop

 if('nav_menu_item' !== get_post_type()) : // ADD THIS LINE  Exclude navigation menu items.

// rest of your loop code 

and at the end of the loop:

Hope this is helpful to someone.

it’s not working?
