From the list of objects, by clicking on any record, the user will view the details of that record. If the editing rights are provided, the User can edit that record or delete it from the detail view.
From the CRM side, if you have managed the page layout of any object ‘section wise’ for the detail page layout, the portal users will get the details section-wise as they access the specific page detail.
Here, the detailed layout will be displayed as per the configuration in the “Detail” block from the page builder.
Note: Once you configured the object’s page layout (edit/detail) section-wise, you also need to sync the layouts from the WordPress admin side from the “Customer Portal Settings -> Authentication”, only then the portal users will get the section-wise page layout of any object.
