I need to display a list of items from a dessert product inventory for the user to make selections from to process an order. The goal is to match the diagram in the attached image. This could be achieved relatively easily in Traditional UI with a repeating dynamic layout, and some local actions, but on Constellation I can so far only choose between a table and a plain field group.

I currently have a List data page “D_GetItems” to retrieve the data from an external database, and I’ve been able to achieve the table display in the attached image. However, the tabular format is obviously not user-friendly for this use-case (having an image of the product from a URL is a must). Additionally, the “Item Inventory” property is set to be sourced from the GetItems data page, and the system automatically assigns it the Query type.

Ideally, the user will be able to select their items from the externally sourced list and set the quantity, then a data transform will copy those items into the “Selected Items” list, which can be used to calculate the order total and can be displayed on a review/payment screen. So far, a field group is not working with the REST Connector and also has no checkbox to select items.
