I tried adding a display rule to one of my Header elements for a specific generic Post Type (video) but there is no option for “Post Type” in my display rules. I could have sworn this was a feature in GP or am I missing something here?
Post Formats aren’t included in the Display Rules. Most straight forward way would be to add a taxonomy to those posts and use that for your display rules.
Tom probably has a function for applying an element to those formats. I can ask if you want. Let me know.
You can select by post type, it’s just not obvious at first. In the display rules you can select “Post”, “Page” or whatever your post type is and then the first option that will appear is “All Posts”.
