I've created a demo page that generates a masonry-style layout from several divs, and then after x seconds runs the jquery.throwable script on said divs.
Here it is: http://output.jsbin.com/yitaru/2/
The problem I've run into is that throwable's "containment:parent" option is not working. The divs themselves are living within multiple parent divs - a ".grid" class (used by the grid generator plugin) and a ".container" class. Neither one seems to be recognized as a parent though, at least by throwable. The divs fall through the bottom of the container and continue falling down the page. Instead I want them to stop within the bounds of the red border.
Any idea what the issue might be here? I expect this is related to a CSS issue and not-so-much a problem with throwable, but I don't know enough about how CSS works to figure this one out on my own. I thought that by nesting the divs in eachother, the parent/child structure would be defined.
