[Resolved] Nested Views not filtering by Parent Taxonomy

I have two custom post types with their own taxonomies:

1) Custom Post Type: Group
Taxonomy: Group Taxonomy
2) Custom Post Type: Sub-Group
Taxonomy: Sub-Group Taxonomy

I want to create a nested view that will display Posts from Sub-Group based on what is selected from the Taxonomy "Group Taxonomy".

For Example, if I navigate to a page of "Group" that has a selected Taxonomy of "GroupA", then it should list all of the 'Sub-Group" posts that share this same taxonomy value.

I have tried the following and it is not working as expected:

1) Create 2 Views, a parent and a child view.
2) The Parent view will contain the child view.
3) The Parent View contains a filter of Taxonomy Filter -> "Group Taxonomy" -> "Set by the page where this view is shown".
4) The Child View contains a filter of Taxonomy Filter -> "Sub-Group Taxonomy" -> "Set by the parent Taxonomy View".

I have defined both Taxonomies with the same values:

Taxonomy : Group Taxonomy
Values: GroupA, GroupB, GroupC, GroupD, GroupE

Taxonomy: Sub-Group Taxonomy
Values: GroupA, GroupB, GroupC, GroupD, GroupE

Currently, no results are being displayed within this nested view. What should happen is the following:

1) Go to a custom post type of "Group".
2) This custom post type has "GroupA" selected within their taxonomy of "Group".
3) This custom post type should now list all of the custom post types of "Sub-Group" that also have "GroupA" selected for their taxonomy of "Child Taxonomy".

Any help is greatly appreciated!

Hi, you can do this with just one View - a View of SubGroup posts. Configure a SubGroup taxonomy Query Filter to use a shortcode attribute like wpv-subgroup, and respond to a term slug (see the attachment). Then place the View in your single Group post template. In the shortcode, use the wpv-subgroup attribute to pass in the slugs of any Group terms associated with the Group post, using the wpv-post-taxonomy shortcode. Those slugs will be passed into the SubGroup Taxonomy filter of the SubGroup View, and only matching SubGroup posts will be displayed. The shortcode structure will look something like this:

[wpv-view name="Your SubGroup View Name" wpv-subgroup="[wpv-post-taxonomy type='group-taxonomy-slug' format='slug' separator=',']"] 

This technique is called passing arguments to Views, and is explained in greater detail here: https://toolset.com/documentation/user-guides/passing-arguments-to-views/

This is exactly what I wanted and it is now working perfectly. Thank you so much! I hope this helps out anyone else who wants to display this type of group listing.
