I'm creating a custom sub-menu for a section of child pages and grandchild pages. The main navigation already displays all top-level pages, so it's not necessary to list them again in this custom menu.
How would I add the code in my custom template file to display a list of a granchild's parent page and its parent's siblings. For example:
-Child page 1-1
-Child page 1-2
-Grandchild page 1-2-1
-Grandchild page 1-2-2
-Grandchild page 1-2-3
-Child page 1-3
-Child page 1-4
When the user is viewing Grandchild page 1-2-1, I would like the sub-menu I'm creating to display Child page 1-1, Child page 1-2, Child page 1-3, & Child page 1-4
(No need to display the top-level pages, or each grandchild page... just the 2nd level of pages – the grandchild's parents and its siblings.)
Thanks in advance!
