Select multiple items, drag them

Question

First, let me tell u that I emphasize this because I don’t even know the name of the concept / method, so I can’t even search for it in google, since I don’t know the keywords, but I try my best to explain this. Feel free to change my content and title as you see fit.

what I want to achieve is: I have a view group containing many child views, or it can be a GridView, I want to block the selection of some of its child views and return the selected / locked items.

any help is appreciated, thank you very much.
