Can a WhatsApp promotion show a swipeable row of dishes (carousel)?

Yes, as a carousel template, and only in the marketing category. It needs 2 to 10 cards, each with an image or video at the top.

• Card count is fixed when you create the template, between 2 and 10.
• Every card needs an image or video header.
• Card text is limited to 160 characters, with up to two buttons per card (quick reply, phone or URL).
• All cards must have the same components.
• Marketing only: carousel cards are not available for other template types.
