Complex Drag and drop interaction
I have a conundrum. I have attached the slide to make this easier to understand. The slide is almost perfectly the way I want it.
I have three TYPES of source drag items (5 ticks, 3 crosses, 2 pictures).
Having 5 ticks, there are 5 spaces that ticks can go. As there is no differentiation between the individual ticks, any of the 5 ticks can go in any of the 5 spaces. THE PROBLEM: Multiple ticks can occupy one space. Is it possible to make some change so that once a space is occupied, it is 'locked out' to other drag items?
This is driving me crazy thinking about it!
Thanking you all!
