Custom post type and sub navigation

Hi all,

I have a main navigation consisting of pages, each page has a number of subpages making up the sub navigation.

I am using a common subnav.php include to display the sub nav for each page. The problem is I have a custom post type ‘recipes’ which is using the ‘single-recipes.php’ and Im unsure about how to display the subnav on this page.

The structure is as follows:

> Recipes & Ingredients
>> Our Process
>> Ingredients Used
>> Highest Rated Recipes
>>> Recipes Listing (single-recipes.php)

So if the current page is ‘Recipes Listing‘ I need the Our Process, Ingredients Used and Highest Rated Recipes sub nav items to still display.

Thanks for help with this.
