CMS & Lightbox + Captions
Display CMS-Managed Captions in Webflow’s Lightboxes
This feature allows you to display a caption inside of Webflow’s lightboxes, which is automatically pulled from the CMS.
Works with CMS-stored images, thumbnails, and captions. Does not support captioning video, due some complexities matching captions to the currently displayed video.
