By adding a scroll selector:

{"_id":"ocio-test","startUrl":["https://www.ociostock.com/play-by-play-lp-1-51-marca-33/"],"selectors":[{"id":"art-link","type":"SelectorLink","parentSelectors":["scroll"],"selector":".nombreProducto a","multiple":false,"delay":""},{"id":"art-namn","type":"SelectorText","parentSelectors":["art-link"],"selector":"h1","multiple":false,"regex":"","delay":100},{"id":"art-nummer","type":"SelectorText","parentSelectors":["art-link"],"selector":"p[itemprop='identifier']","multiple":false,"regex":"","delay":100},{"id":"art-info","type":"SelectorText","parentSelectors":["art-link"],"selector":"h2","multiple":false,"regex":"","delay":100},{"id":"art-stock","type":"SelectorText","parentSelectors":["art-link"],"selector":"span.parcialmentedisponible","multiple":false,"regex":"","delay":0},{"id":"art-pris","type":"SelectorText","parentSelectors":["art-link"],"selector":"span[itemprop='price']","multiple":false,"regex":"","delay":100},{"id":"art-bild","type":"SelectorImage","parentSelectors":["art-link"],"selector":"img[itemprop='image']","multiple":false,"delay":100},{"id":"scroll","type":"SelectorElementScroll","parentSelectors":["_root"],"selector":"ul.ninguna","multiple":true,"delay":"2000"}]}
