I'm struggling with a problem relating to a drag and drop system. I’m designing a complex system that allows the user to configure a decision tree to get to a price value.
This system simplified is identical to the one on the mockup below.
I’m using a drag and drop approach to allow the user to add “Taxes“ to products. This approach works well if you want to add only one tax to a product at a time. I drag a value from the right column to the tree individually.
My problem is that i want to allow adding multiple taxes to multiples products at the same time, for example, I want to add taxes 3 and 4 to products 1 and 3 at the same time.
It´s easy to select multiple taxes at the same time, but how about adding them to the tree?
Do you have any suggestions?
Thanks for your help
