How may we implement the “items:” in our custom detail to display the items count as in the product in order detail?
Furthermore, how can I get the number of currently displayed detail items and the total detail items respectively in the method of detail's client module?
Just review how the logic of the summaryCountValue, summaryCountCaption and updateSummary method is implemented in the OrderProductDetailV2 schema and perform the same setup in your detail. You only need to debug the logic execution, all the logic is client-side.
