I read in Help that in order for a collection to appear (as a scroll) on the product page, it needs to have a banner. This doesn’t seem to be the case in my store, but I want to check here to see if I am missing something. Am I?
I would not know how to check the veracity of the info you have read on the Zazzle help page. I just use simple banners (usually from photos I have already uploaded for other purposes) so that I can get it done in a flash and I never have to worry about it.
My products show collections that don’t have banners also. Maybe this is outdated, and the Help hasn’t been updated yet?
