wordpress remove add new button

// You can do this when registering your post type. Like this:

register_post_type(
	'custom_post_type',
  	array(
    	'description' => __( 'description', 'textdomain' ),
      	// etc, etc. Important to remove the 'add new' button:
      	'map_meta_cap' => true,
      	'capabilities' => array( 'create_posts' => false )
    )
);
