create a menu based on the parent of a drupal book

Question

I've been working with the book module bundled with drupal 7 and have a question. Say i have a book x, and this book contains 4 pages which each have 2 children giving a structure like this:

• Book x
  • Subheading 1
    • Page 1
    • Page 2
  • Subheading 2
    • Page 1
    • Page 2
  • Subheading 3
    • Page 1
    • Page 2
  • Subheading 4
    
    • Page 1
    • Page 2

What I want to do is create a menu that will sit at the bottom of the page which displays links based on these 4 subheadings, i.e. if you were viewing Subheading 1 the menu would display links to the 2 child pages of the subheading. Is this possible?

Answer 1

I figured out my issue, turns out my theme_menu_link function was hiding the book menu block. Once I realised this I placed the block alongside my main menu on the block pages, and used my theme_menu_link to style it.
