    <p>Are you going to allow more than one instance with your draggable objects? then use the helper and append option:</p> <pre><code>$(".tag_cell").draggable({ helper: 'clone', appendTo: 'div#myHelperHolder' }); </code></pre> <p>Then in your css you can set the zindex of div#myHelperHolder to be 999. If not, then try just using the zindex option:</p> <pre><code>$(".tag_cell").draggable({ zIndex: 999 }); </code></pre> <p>I would also consider setting addClasses to stop the plugin from adding all those annoying classes that waste processor speed.</p> <p><strong>UPDATE: I HAVE A NEW SOLUTION</strong></p> <p>Okay after playing with it for a bit I came up with this: the scroll option doesn't stop the child from being hidden with overflow. I've read some other posts and I cant find a single solution. But I came up with a bit of a work-a-round that gets the job done.</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;script type="text/javascript" src="http://www.google.com/jsapi"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; google.load("jquery", "1.4.0"); google.load("jqueryui", "1.7.2"); google.setOnLoadCallback(OnLoad); function OnLoad(){ var dropped = false; $(".tag_cell").draggable({ addClasses: false, revert: 'invalid', containment: '#tagFun_div_main', helper: 'clone', appendTo: '#tagFun_div_helper', start: function(event, ui) { dropped = false; $(this).addClass("hide"); }, stop: function(event, ui) { if (dropped==true) { $(this).remove(); } else { $(this).removeClass("hide"); } } }); $("#tf_dropBox").droppable({ accept: '.tag_cell', hoverClass: 'tf_dropBox_hover', activeClass: 'tf_dropBox_active', drop: function(event, ui) { dropped = true; $.ui.ddmanager.current.cancelHelperRemoval = true; ui.helper.appendTo(this); } }); } &lt;/script&gt; &lt;style&gt; div#tagFun_div_main { display:block; width:800px; height:400px; margin:auto; padding:10px; background:#F00; } div#tf_div_tagsReturn { display:block; width:200px; height:100%; float:left; overflow:auto; background:#000; } div#tf_div_tagsDrop { display:block; width:200px; height:100%; float:right; background:#0F0; } div#tf_dropBox { display:block; width:100%; height:250px; background:#F0F; } span.tag_cell { display:block; width:25px; height:25px; margin:1px; float:left; cursor:pointer; background:#0FF; z-index:99; } span.tag_cell.hide { display:none; } div#tf_dropBox.tf_dropBox_hover { background:#FFF !important; } div#tf_dropBox.tf_dropBox_active { background:#333; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="tagFun_div_main"&gt; &lt;div id="tf_div_tagsReturn"&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;span class="tag_cell"&gt;&lt;/span&gt; &lt;/div&gt; &lt;div id="tf_div_tagsDrop"&gt; &lt;div id="tf_dropBox"&gt;&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;div id="tagFun_div_helper"&gt; &lt;!-- this is where the helper gets appended for temporary use --&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I pasted my entire code so you can try it out. Here is a brief description: When you start to drag an item it hides the original, clones it, then appends the clone to a container outside the overflow area. Once dropped it removes the original and moves the clone into the drop zone. Great so now we have fixed that overflow issue but run into some others. When you drop the clone item into the drop zone it disappears. To stop that from happening I used this method:</p> <pre><code>$.ui.ddmanager.current.cancelHelperRemoval = true; </code></pre> <p>Now we have stopped the helper from being removed but it remains in "div#tagFun_div_helper" while the original draggable item has reappeared.</p> <pre><code>ui.helper.appendTo(this); </code></pre> <p>This will transfer the helper from "div#tagFun_div_helper" into our drop zone.</p> <pre><code>dropped = true; </code></pre> <p>This will tell our stop function to delete the original item from the group instead of removing the ".hide" class. Hope that helps!</p>

    1. COthank you for your reply. i didn't go with using helper/clone but i did set zindex to 999, the problem is still occurring. i really don't know what the problem is, i'm starting to wonder if this is possible, but i have to imagine people contain draggable elements in scrolling div's all the time. thanks for the addClasses suggestion, i implemented that. please share any other suggestions/thoughts you might have on this scrolling issue.

    2. COI have updated my response to include a new solution. check it out. Also I noticed one of your div id's have a space before the first letter <div id=" tf_div_tagsDrop">. I don't think it was affecting anything, but I just thought you should know :-)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
