Hi guys how would I go about doing a 3 stage cascaded dropdown box? I have a nintex sharepoint list. I have the child on one list and the other 2 on another list.
I currently have a 2 stage one. I also want to have an add button so I can submit more the child choice into another column. I know I have to submit data but I don't know how to do it. If anyone can help it'll be great thanks!
