    <p>I am trying to write some code that allows SVG elements to be dragged around. This is pretty easy with jQuery, jQuery UI and jQuery SVG, and works fine in Firefox, but in Chrome when I drag the SVG element, an offset is apparently added to its coordinates. I can't see anything I'm doing wrong, or discover any known bug in this area.</p> <p>I've constructed a small example that illustrates the problem:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Foo&lt;/title&gt; &lt;style type="text/css"&gt; &lt;/style&gt; &lt;script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="http://keith-wood.name/js/jquery.svg.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(function() { var svgOnLoad = function () { var svg = $('#canvas').svg('get'); $('#piece') .draggable() .bind('drag', function (event, ui) { // Update transform manually, since top/left style props don't work on SVG var t = event.target.transform.baseVal; if (t.numberOfItems == 0) { t.appendItem(svg.root().createSVGTransform()); } t.getItem(0).setTranslate(ui.position.left, ui.position.top); }); } $('#canvas').svg({loadURL: "foo.svg", onLoad: svgOnLoad}); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="canvas" style="width: 100%; height: 100%;"&gt;&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>where foo.svg is just:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt; &lt;svg version="1.1" xmlns="http://www.w3.org/2000/svg" width="450" height="450"&gt; &lt;rect id="piece" width="50" height="50" x="100" y="100" /&gt; &lt;/svg&gt; </code></pre> <p>An online version can be found at:</p> <p><a href="http://jsfiddle.net/rrthomas/v477X/2/" rel="nofollow">http://jsfiddle.net/rrthomas/v477X/2/</a></p>

    1. COA live example, +1. This is fine as-is, but you may find it useful to use _jsfiddle_ in the future for examples - people can fork your code and try/suggest a fix more easily.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
