Combining Lines

You can easily combine split products back into a single product using the Combine lines button.

When the product is split in the shopping cart, tap the selected products by highlighting them in green, which will open the editing window. You can drag or close the editing window by pressing the cross, after which you can select multiple lines.
After selecting the same products with the split price, tap the Combine lines button in the opened editing window to combine the product into the same line.
