How can i publish this kind of post
First time seeing this type of posts, but yeah it looks very neat 
Hopefully someone will enlight us about it
can you share the full screenshot I need to see the exact placement of that post and what’s around it.
Can you provide a link?
I don’t see whats special about this
they’re called carousels and originally was Watch More, it used to be quite lucrative but doing this now will likely get you unpublished.
You can create these posts in either Ad Manager or Creator Studio
