AL has some limitations compared to C/AL, but drop-down functionality is not one of them. You can do the same things in both. To show certain fields in the drop-down list, create the Dropdown field group in your table: https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-field-groups As for the Zip code selection that populated several fields, here you need to do some coding to make it behave like this. Controls with lookups to the Post Code table call the function PostCode.ValidateCity in their OnValidate triggers. You will need something like this too - in the trigger OnValidate, assign all the field you need populated.
