I've seen similar problems when using scrollable divs and the drag/drop features of Scriptaculous. It seems to be caused by the fact that Scriptaculous's drag/drop features don't account for the scrolling of intermediate widgets between an element's real position on the screen and its position relative to the document.
It's discussed here a bit: https://prototype.lighthouseapp.com/projects/8887/tickets/122-scrollbar-causes-drag-drop-to-fail#ticket-122-6 After spending some time trying to figure out where to fix this issue, I ended up writing a couple of hackish scripts to find the REAL scrolling x/y coordinates, even when nesting scrolling divs as follows: function getTotalScrollLeft(n) { var ret = 0; if (n.parentNode) ret = getTotalScrollLeft(n.parentNode); if (n.scrollLeft) ret = ret + n.scrollLeft; return ret; } function getTotalScrollTop(n) { var ret = 0; if (n.parentNode) ret = getTotalScrollTop(n.parentNode); if (n.scrollTop) ret = ret + n.scrollTop; return ret; } On Tue, Jul 6, 2010 at 8:17 AM, Yuri Leikind <yuri.leik...@gmail.com> wrote: > Hello all, > > I am stuck here with a problem. > > There's a scrollable div on a page (overflow-y: scroll) with > draggables inside, I will call them draggables type A for the sake of > simplicity.
