Jotform prodcuct order form cutting off when categories are expanded

Hello. Having an issue with a Jotform product order form cutting off in the iframe when categories are expanded. Need to somehow increase the height of the iframe or make it expand as the form does. Elsewhere people have suggested disabling Ajax loading but my template does not seem to allow this

The page url doesn't work. Can you check it again?
