I would like to use a gallery as a method to select items from a collection. I think I know how to use code to record what items get picked ( odd # of clicks on an item) and unpicked (even # of clicks on an item). But I would also need some sort of UI effect to highlight those gallery items that get selected (e.g. Changing image colour, or placing a frame over the image, etc)
Any ideas on how this could be implemented?
