I'm new to developing on the wordpress platform. I'm sure what I'm about to ask has been done before, but I just can't seem to find the tutorials for it.
I want to create a partial hierarchical tree that expands and collapses depending on which page you are on. For example, if I'm on the "Battery" page of an inventory site, the navigation should be:
- - Computers
- - TVs
- - Miscellaneous
- - - [ Batteries ]>selected
- - - Power Cords
If I am on the "Love Seat" page, then the hierarchy should be
- - Sofas
- - - Full Sets
- - - [ Love Seats ] > selected
- - Beds
- - Dining Room
So as you can see, the tree only shows the selected page, it's siblings, it's parent and parent siblings, grand parent and grand parent siblings etc....
How do I achieve this?
