In my application, I have let’s say 100 nodes. Out of those 100, I have requirement that 50 nodes can be dropped in Group A ONLY, and the remaining 50 nodes can be dropped in Group B ONLY.
So I want to restrict the dropping of nodes in wrong groups. How can I achieve this?
I have implemented memberValidation function but it’s not helping me. Even though I return false from memberValidation function it still adds node to the group.
