    <p>I'm trying to enable <strong>HTML5 drag and drop on a custom polymer element</strong> but it doesn't work. Without polymer it's possible to just add the <code>draggable</code> attribute.</p> <p>Here is my code in Dart:</p> <h3>my_component.html</h3> <pre class="lang-html prettyprint-override"><code>&lt;polymer-element name="my-component"&gt; &lt;template&gt; &lt;style&gt; @host { :scope { display: block; } } div { background-color: red; width: 200px; height: 200px; } &lt;/style&gt; &lt;div&gt; Drag me &lt;/div&gt; &lt;/template&gt; &lt;script type="application/dart" src="my_component.dart"&gt;&lt;/script&gt; &lt;/polymer-element&gt; </code></pre> <h3>my_component.dart</h3> <pre class="lang-dart prettyprint-override"><code>import 'package:polymer/polymer.dart'; @CustomTag('my-component') class MyComponent extends PolymerElement { MyComponent.created() : super.created(); } </code></pre> <h3>test.html</h3> <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;link rel="import" href="my_component.html"&gt; &lt;script type="application/dart"&gt;import 'package:polymer/init.dart';&lt;/script&gt; &lt;script src="packages/browser/dart.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;my-component draggable="true"&gt;&lt;/my-component&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I also tried extending directly from an HTML Element. This didn't work either.</p> <p><strong>Any ideas how a polymer element can be made draggable?</strong></p> <p>Edit: There is a <a href="https://code.google.com/p/dart/issues/detail?id=15564">Bug Report</a> for this.</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.
