You need to set up pagination with a loop using element click
and then use link selector to grab each link
then scrape that page
Here is an example, you need to put in the text selectors on the details page
{"_id":"licitacionesultimas","startUrl":["https://contrataciondelestado.es/wps/portal/licRecientes"],"selectors":[{"id":"tabla","type":"SelectorElementClick","parentSelectors":["root"],"selector":"div#FLYParent","multiple":true,"delay":"4000","clickElementSelector":"input#viewns_Z7_BS88AB1A0GSM10A6E365201G25\:liciRecientes\:siguienteLink.botonEnlace","clickType":"clickMore","discardInitialElements":false,"clickElementUniquenessType":"uniqueHTML"},{"id":"Link","type":"SelectorLink","parentSelectors":["tabla"],"selector":"a.sinEstilo","multiple":false,"delay":0},{"id":"Set up elements here","type":"SelectorText","parentSelectors":["Link"],"selector":"fieldset#DetalleLicitacionVIS_UOE ul.altoDetalleLicitacion","multiple":true,"regex":"","delay":0}]}
