BP_Walker_Nav_Menu:: (3 methods):
  do_walk()
  walk()
  start_el()


Class: BP_Walker_Nav_Menu  - X-Ref

Create HTML list of BP nav items.

do_walk( $elements, $max_depth, $args = array()   X-Ref
Display array of elements hierarchically.

This method is almost identical to the version in {@link Walker::walk()}.
The only change is on one line which has been commented. An IF was
comparing 0 to a non-empty string which was preventing child elements
being grouped under their parent menu element.

This caused a problem for BuddyPress because our primary/secondary
navigations don't have a unique numerical ID that describes a
hierarchy (we use a slug). Obviously, WordPress Menus use Posts, and
those have ID/post_parent.
