Completely Fluid (CF) Flowlines
(Icon: Shows an Ad size that can be STRETCHed in both the X and Y, any direction, to essentially be a completely fluid asset)
This format is for cases where you do not know what size you want your creative to fit into and you want to have a completely fluid creative that works everywhere. Essentially any dimension. Creative agencies that build our creative may not know what the target may be and want to make it so that they have a completely fluid creative that could be delivered to the media agencies.
Presently this type is unavailable in the self-serve version of Narrator, but is being developed and tested for programmatic creative delivery.
