Using Content Sources | YOOtheme Documentation (WordPress)

All builder elements are able to load dynamic content. First, you need to select a content source which defines fields available for mapping. It can be selected in the Advanced tab of an element under Dynamic Content. For elements which have multiple content items, for example the Grid or the Slideshow element, the Dynamic Content option can be found in the Advanced tab of each item and not of the element itself. This way each item can have a different content source.
