Hey Dan,
i dont test your stuff, but this should work.
**Here’s part my YAML:**
header.customer_videos:
ordering@: 10
type: list
collapsed: true
label: Videos
fields:
.video:
type: textarea
size: large
label: Video Embed
**Here’s what I have in my template:**
{% for item in page.header.customer_videos %}
{{ item.video }}
{% endfor %}
I just changed video to items for readability (it would also work with video.video)
