Yes, this is in summary what the other user did, and the only that leads to the goal set.
I cannot state that it is part of the intended and in past released integration, where we integrated Elementor so you can add Toolset elements to its templates.
This is available when you create Elementor Templates, which you apply to your content, as widgets.
Forms, Views, and Fields (as dynamic options)
So there are a few logical consequences of this:
- you could design the archive with Views Archives and then the templates for the posts in that loop with Elementor.
- However, since archives are more templates than single data, and in posts, we would suggest using Elementor Templates to show Toolset Data, it is safe to say that the same should be done on archives.
Especially, note the ability of Elementor's templating of child terms, this is something that is natively not possible in Toolset - it seems possible in Elementor.
Loading a View with the Query parameter as you mention is not dangerous and has to work, just remember that if something would be to alter the Archive Query... The view would have to obey that and eventually fail.
This is not the case here, Elementor just provides the templates for the archives, not the queries.
Inserting a View to such archive will return the posts connected to the terms as in the current archive.
It should hence be OK to do this, even if it is not part of the documented how to.
Note here the documented how to:
https://toolset.com/documentation/user-guides/using-toolset-with-elementor-page-builder/design-archive-pages-for-custom-post-types/
It leads here https://toolset.com/documentation/getting-started-with-toolset/customize-post-archives/
After reading that, it's clear we do not document or "support" templating archives with Elementor as Elementor is missing from the particular list, leaving us with designing without any page builder option only.
However, what that DOC does not take into account is your decision and Elementor's AddOns.
I have informed our DOC responsible about the "out of date" statement on https://toolset.com/documentation/user-guides/using-toolset-with-elementor-page-builder/design-archive-pages-for-custom-post-types/
I say out of date because Elementor as well evolved, and back when that Document was written, eventually, the add-ons were not at today's popularity.
Eventually, we will update the doc - I will leave this decision to the ones in charge of this.
I hope to have answered any doubts, if not please let me know.
