Drag and Drop centered positioning with overlaying objects
First I have to admit, that my english could be better, Im from Germany. I hope I can explain my request well enough.
I am currently working on an E-Learning-Application for music students. I want to create a drag n drop task, in which they shall take notes and signs and drag them to the right place on empty music lines. The notes are no problem, Thats working fine, because they are small enough. The signs are overlapping multiple drop-targets. So either I select the "centered drop" in the menu and the signs are realy hard to place at all, or I dont select it and many wrong positionings are going to be declared as correct.
My question is: Is there a possibility to just have a part of a Group be selected as the drag-item for the drop-target? I haven't found it yet. In this case I could attach an invisibe rectangle to the sign, that would fit into the drop-targets perfectly.
Hoping you can hlp me out
