Drag and Drop overflow auto

Reported by srinath | October 8th, 2009 @ 08:57 AM

Hi all,
I am trying to create a web app that will let you drag
items from a left pane to a right pane. These panes must have
overflow: auto on because there will definitely be more data in them
than can fit in the provided space. The problem is that when overflow
is set to auto, the div expands when the draggable object reaches the
extents instead of the object existing outside that div while being
I want to drag an item from left pane and drop on right pane target div.
This is not working when using overflow:auto, as the item is going under right pane and not visible .
This is my code :

LeftPane {

width: 150px; / optional, initial splitbar position /
margin: 10px 0px 10px 10px;
background: #ffffff;
border: #b6b6b6 1px solid;

LeftPane li.sorting {

float: left;
margin: 4px;
padding: 4px;
border: 1px solid #ccc;

LeftPane li.sorting:hover {

float: left;
margin: 4px;
padding: 4px;
border: 1px solid #666;
cursor: move;
} /* Right-side element of the splitter. /

RightPane {

margin: 10px 10px 10px 0px;
background: #ffffff;
border: #b6b6b6 1px solid;

    Here is what I wrote to have it running under IE 8.0.6 & Firefox 3.6.3:

    Make draggable the elements (with border) in the "width:100px;overflow:auto" container:
    function makeDraggable(container,tag) {

    if(!container || !tag) { return false; }
    $(container).select(tag).each( function(o) { new Draggable(o,{

    starteffect: function(e){makeDragVisible(container,e);},
    endeffect: function(e){e.setStyle({'position':'','width':'','cursor':''});},
    zindex: 1000
    // , revert: ... // the other options

    }); });


    function makeDragVisible(container,element) {

    if(!container || !element) { return false; }
    var i=$(container).getStyle('width');
    // $(container).setStyle({});


    Important notes: (1) the z-index is repeated (2) notice the container loss of style at the end of 'starteffect'. Cursor and width are simply there to keep the drag user friendly.

    I hope it helps.
