Sort of understand,
This is the support thread from your colleauge Luo Yang. I tried following it, but got stuck on the "Views" portion. He mention setting a widget on the left, and info on the right.
I suggest you try these:
1) Create two post types:
- Brand
- Model
https://toolset.com/documentation/user-guides/create-a-custom-post-type/
2) Setup one-to-many relationship between post type "Brand" and "Model"
https://toolset.com/documentation/post-relationships/
So you can setup "Brand" and "Model" posts like this:
Brand A
-- Model 1
-- Model 2
Brand B
-- Model 3
3) Setup many-to-many relationship between post type "Model" and "Product"
https://toolset.com/documentation/post-relationships/how-to-set-up-post-relationships-using-toolset/
When you edit a single product post, you will be able to connect it with multiple "Model" posts
4) Create a post view, for example "my-view", with option "Full custom display mode":
- query product posts,
- in section "Custom Search Settings", enable option "AJAX results update when visitors change any filter values"
- in section "Search and Pagination", setup the post type relationship filter by with "Model" and "Product", see screenshot:
post-relationship-filters.JPG
- in section "Loop Editor" display the product posts information
5) Create a wordpress page, display above view's search result only, for example:
[wpv-view name="my-view" view_display="layout"]
6) In the sidebar, display an "WP Views Filter" widget of view "my-view"
Then it should be able to achieve what you want:
Ajax filter on the sidebar. A user should be able to choose Brand = Mercedes, then only Mercedes model numbers show
