Hi! Can you please add support of optional scrollable element? I think this can be achieved by simple check if, for example, prop "parentId" is not empty and then if not - use document.getElementById(this.parentId).scrollTop and document.getElementById(this.parentId).offsetHeight instead document.body.scrollTop and document.body.offsetHeight respectively. I'm not sure if there's gonna be some problems with this solution, but it worked for me. Huge thanks for plugin, btw!
