I am working on a site with listing photos. Each listing has more than 25 images, so via the API I split the gallery into 2 galleries inside of the CMS collection. So could I create one single gallery on the listing page and feed in both galleries from the CMS?
A gallery is just a collection list, probably containing a lightbox element.
What you might do is have two collection lists setup, each with the exact same styling and configuration but bound to the two gallery fields separately.
Then use Finsweet’s CMS combine to merge those two lists so they flow as one in your grid layout.
