Hi, I have a particular use case for a tourism website where there is a relationship between two different taxonomies. I’m aware that this can be achieved through hierarchical taxonomies but I would like to have two separate lists for filtering.
For example, suppose we have a custom post type called Tours and two custom taxonomies associated with this post type called Continents and Countries. The issue arises when a particular tour travels to multiple continents. If we have a tour that goes to both Morocco in Africa and Spain in Europe, the Continents taxonomy would have Africa and Europe, while the Countries taxonomy would have Morocco and Spain. Now, if I create two taxonomy filters for both Continents and Countries in my search & filter form, if a user clicks Europe within the Continents taxonomy filter, both Morocco and Spain would show up in the Countries taxonomy filter. Similarly, if a user clicks Morocco in the Countries taxonomy filter both Europe and Africa would show up in the Continents taxonomy filter.
I’m aware that this is the intended behavior but is there a way for me to specify a relationship (i.e. if I had a list of all countries within a continent) such that when a user selects Morocco in the Countries taxonomy filter only Africa will show up in the Continents taxonomy filter and vice versa.
Your help is very much appreciated. Thanks.
