How to Create a “Partial” Hierarchical Tree for Navigation

  • 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:

    Home
    – Electronics
    – – Computers
    – – TVs
    – – Miscellaneous
    – – – [ Batteries ]>selected
    – – – Power Cords
    – Furniture
    – Lighting

    If I am on the “Love Seat” page, then the hierarchy should be

    Home
    – Electronics
    – Furniture
    – – Sofas
    – – – Full Sets
    – – – [ Love Seats ] > selected
    – – Beds
    – – Dining Room
    – Lighting

    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?

    thanks
