When I first thought about creating the 'breadcrumb trail' I thought about creating a new sub. When I started this I realised that
it is just the same tree but walked backwards and can be accomplished by reversing the parent-child relationship in the tree tag.
You just need to tell the [tree] tag to start at the end and it all works.

In your above output you still have the master and subordinate the way round you would for a category list - you need to swap these
around.

Trust me - I have this working.

good luck,

Jonathan.
