Rectangles following a path


I am triying to create some rectangles following a path. I would like that those rectangles have a random location but next to each other. I have done something similar but rectangles are touching each other and is just a grid of rectangles disordered. I place some images that would explain mi idea.

I would need to implement in the definition that my rectangles could follow a path and also that could be together but just touching each other

Thanks in advance
