I'm wondering if there's a way to list all custom taxonomies that are siblings to the current page (e.g. in my single.php)?
For example my taxonomy is as follows
Categories
- -- Ancient
- +++ Greek
- ///// Plato
- ///// Socrates
- +++ Roman
- +++ Indian
- -- Classic
- -- Modern
I'd like to create a sidebar that lists all other items that have the same parent (including descendants of other siblings - e.g. "Greek" page would list "Roman" and "Indian". The "Ancient" page would include links to "Ancient >> Greek", "Ancient >> Roman", "Ancient >> Indian", "Classic" and "Modern" Pages. )
Is this possible with custom taxonomies? How can I achieve it?
Thanks!
*EDIT*
Also, for reference, I am working with the following blog posts which give a more detailed insight into what I need, I simply am having trouble customizing it to the specifications I mentioned in my original post:
