Display posts by Custom Taxonomy
If you want to get posts that all belong to a specific taxonomy - you can do this with Divi Machine.
In the Archive Loop module, inside the "Loop Options" tab there are the settings
1) Choose Your Taxonomy - this will get all the posts that have this taxonomy
2) Include Custom Taxonomy (comma-separated) - here you define the taxonomy values.
So for example, if I want to get all posts that have the taxonomy brands and the values as "Apple" and "Android" - you will do as the screenshot below
