Facebook Ads has introduced a new display option for carousel ads called “Collage.” It allows advertisers to combine materials uploaded to a carousel and display them together as a collage.
The setting is located at the ad level in the Format display options section. Also available there are the Single image or video and Video slideshow options, which allow carousel materials to be shown as a single image or video, or as a video slideshow.
The feature may not be available in all ad accounts.
