Hi I want to create be-input in my extension for a paired list: qty discount 1 0% 2 5% 4 10% ... and so on. I looked in "doc_core_api" but couldn't find a smart way to fix it. I know it can be done by creating a comma separated list (1|0;2|5;4|10; ...) in a plain input field but that isn't elegant. Anyone with a good idea. Reagrds Peter
