This is a fairly standard paginator design these days. So you can use type: Element Click with click type: Click More. Something like the sitemap below. I set a 3.5 sec delay between clicks:
{"_id":"gevel-online-test","startUrl":["http://www.gevel-online.nl/catalogue"],"selectors":[{"id":"Paginator","type":"SelectorElementClick","parentSelectors":["_root"],"selector":"div.row.flex.flex-wrap","multiple":false,"delay":"3500","clickElementSelector":"input.btn.next.wp-dynamic-btn","clickType":"clickMore","discardInitialElements":"discard-when-click-element-exists","clickElementUniquenessType":"uniqueCSSSelector"},{"id":"Row wrappers","type":"SelectorElement","parentSelectors":["Paginator"],"selector":"div.margin-bottom","multiple":true,"delay":0},{"id":"Company and link","type":"SelectorLink","parentSelectors":["Row wrappers"],"selector":"a.ng-binding","multiple":false,"delay":0},{"id":"Stand","type":"SelectorText","parentSelectors":["Row wrappers"],"selector":" span[ng-bind='item.stand']","multiple":false,"regex":"","delay":0}]}
