@alzibaba, thanks for contributing, but the example you screenshotted was for a single Reference Category called "Category" that is indeed only a single reference and I don't need help with it. You also jumped back to the home page dynamic list instead of the Vendor Collection Template page where I have the problem.
I want to filter multiple reference categories in a dynamic list on a Collection Template page.
Your example of home page categories is not what I'm trying to do. But to follow through your example, if you have placed one of your blog posts into both "Leadership" and "Customer Experience" categories, then I'd want to list both of the categories (and only those two categories) at the top of the blog post when you open the post on its own Collection Template page. Just like listing tags at the top of a blog post.
@PixelGeek Any progress on an answer for me for filtering a multi reference on a Collection Template page?
