@rodmans Hi, it seems that after choosing any exhibitor profile that can not be found on the first page and 'clicking' on the 'back' button you will get redirected back to the first page(seems like a technical glitch within the website), therefore you will most likely run to an infinite loop if you are using a 'pagination' selector.
The most viable way to scrape all of the available exhibitors will require applying additional filters by using an 'Element click' selector.
Example:
{"_id":"salonemilano-it-belgium","startUrl":["https://www.salonemilano.it/en/exhibitors"],"selectors":[{"id":"click-1","parentSelectors":["_root"],"type":"SelectorElementClick","clickElementSelector":"div:nth-of-type(11) span.MuiIconButton-label","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":1000,"discardInitialElements":"do-not-discard","multiple":true,"selector":"body"},{"id":"click-2","parentSelectors":["_root"],"type":"SelectorElementClick","clickElementSelector":"div.MuiGrid-grid-xs-12 div.MuiBox-root:contains(\"Belgium\"):nth(0)","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":1000,"discardInitialElements":"discard-when-click-element-exists","multiple":true,"selector":"body"},{"id":"click-3","parentSelectors":["_root"],"type":"SelectorElementClick","clickElementSelector":"div.MuiPaper-rounded","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":2400,"discardInitialElements":"discard-when-click-element-exists","multiple":true,"selector":"body"},{"id":"telephone","parentSelectors":["click-3"],"type":"SelectorText","selector":"a[href*=\"tel:+\"]","multiple":false,"delay":0,"regex":""},{"id":"e-mail","parentSelectors":["click-3"],"type":"SelectorElementAttribute","selector":"a[href*=\"mailto\"]","multiple":false,"delay":0,"extractAttribute":"href"},{"id":"click-back","parentSelectors":["click-3"],"type":"SelectorElementClick","clickElementSelector":"div[style=\"width: 70%; margin: 0px auto; max-width: 1250px;\"] > div.MuiGrid-root.MuiGrid-container button[variant=\"noneInverted\"]","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":2000,"discardInitialElements":"discard-when-click-element-exists","multiple":true,"selector":"div[style=\"width: 70%; margin: 0px auto; max-width: 1250px;\"] > div.MuiGrid-root.MuiGrid-container"}]}
