    <p>I'm trying to make my first Firefox extension, that replaces the new tab page with a more Chrome-like tab page. one of the features is tiles of your "most visited sites," that you can drag-and-drop to reorder. I have them dragging and dropping, but I have no idea how to save the new locations of the DIVs. </p> <p>This is the script I'm using:</p> <pre><code>$(document).ready(function(){ jQuery.fn.redswap = function(options){ var selectedItems=this; redsettings = jQuery.extend({ speed:"Medium", opacity:0.7 }, options); $(selectedItems).mouseover(function(){ $(selectedItems).disableSelection(); $(selectedItems).droppable({ drop: function(event, ui) { dropindex=$(selectedItems).index(this); var dragposition=$(selectedItems[dragindex]).position(); var dropposition=$(selectedItems[dropindex]).position(); withDifference=parseInt(dragposition.left)-parseInt(dropposition.left); heightDifference=parseInt(dragposition.top)-parseInt(dropposition.top); $(selectedItems[dropindex]).animate({ left:'+='+withDifference, top:'+='+heightDifference },redsettings.speed,function(){ }); $(selectedItems[dragindex]).animate({ left:'+='+(withDifference*(-1)), top:'+='+(heightDifference*(-1)) },redsettings.speed,function(){ //Complete }); }, }); $(this).draggable({ opacity:redsettings.opacity, helper: 'clone', containment: 'parent', scroll: false, drag:function(event, ui){ dragindex=$(selectedItems).index(this); } }); }); }; }); // Settings $(document).ready(function(){ $("#wrapper").tabs(); $("div[id*='box']").redswap({ speed:'slow', opacity:.75 }); }); </code></pre> <p>And this is my HTML:</p> <pre><code>&lt;div id="1box" class="item"&gt; &lt;a href="http://www.google.com/reader/view"&gt;&lt;img src="thumbs/01.png" border="0" /&gt; &lt;h1&gt;Google Reader&lt;/a&gt;&lt;/h1&gt;&lt;a href="#" class="x"&gt;&lt;/a&gt;&lt;a href="#" class="tack"&gt;&lt;/a&gt; &lt;/div&gt; &lt;div id="2box" class="item"&gt; &lt;a href="https://mail.google.com/"&gt;&lt;img src="thumbs/02.png" border="0" /&gt; &lt;h1&gt;Gmail&lt;/a&gt;&lt;/h1&gt;&lt;a href="#" class="x"&gt;&lt;/a&gt;&lt;a href="#" class="tack"&gt;&lt;/a&gt; &lt;/div&gt; &lt;div id="3box" class="item"&gt; &lt;a href="http://calendar.google.com/"&gt;&lt;img src="thumbs/03.png" border="0" /&gt; &lt;h1&gt;Google Calendar&lt;/a&gt;&lt;/h1&gt;&lt;a href="#" class="x"&gt;&lt;/a&gt;&lt;a href="#" class="tack"&gt;&lt;/a&gt; &lt;/div&gt; &lt;div id="4box" class="item"&gt; &lt;a href="http://www.twitter.com/"&gt;&lt;img src="thumbs/04.png" border="0" /&gt; &lt;h1&gt;Twitter&lt;/a&gt;&lt;/h1&gt;&lt;a href="#" class="x"&gt;&lt;/a&gt;&lt;a href="#" class="tack"&gt;&lt;/a&gt; &lt;/div&gt; </code></pre> <p>The HTML isn't final yet, but it does drag and drop. Any idea how I can save the new order of the DIVs, so that when I close out and open it up again, it's the new configuration? If it can't be done with this script, then I'm fine being pointed to a new version.</p> <p>Keep in mind I'm very very new to JavaScript, so please treat me like I'm an idiot :)</p> <p>Also, if you're interested in helping me on the coding part of things, send me a message.</p>

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.
