    <p><a href="http://plnkr.co/edit/Cvms35UyKOV1iwUmvLqN" rel="nofollow noreferrer">Plunker demonstrating code</a></p> <p>I have a <code>&lt;div&gt;</code> element with the directive <code>dragAndDrop</code> set as an attribute:</p> <pre><code>&lt;div ng-class="divClass" drag-and-drop&gt;Drop files here&lt;/div&gt; </code></pre> <p><em>(as a side, and less important note, ng-class is not behaving as expected, but that's a <a href="https://stackoverflow.com/questions/15419839/angularjs-directive-scope-not-setting-ng-class-on-element">separate issue</a>)</em> What I would like is for users to drag and drop files from their desktop to the div. Upon doing so though, I use <code>angular.bind()</code> to detect the drop event. Of course once they drop, I call <code>e.stopPropagation()</code> and <code>e.preventDefault()</code>, but the page continues on with redirecting the page regardless. What am I doing wrong that would prevent the two aforementioned methods from executing?</p> <p><code>dragAndDrop</code> directive:</p> <pre><code>directive('dragAndDrop', function() { return { restrict: 'A', link: function($scope, elem, attr) { elem.bind('dragenter', function(e) { e.stopPropagation(); e.preventDefault(); // still can't get this one to behave: // https://stackoverflow.com/q/15419839/740318 $scope.divClass = 'on-drag-enter'; }); elem.bind('dragleave', function(e) { e.stopPropagation(); e.preventDefault(); $scope.divClass = ''; }); elem.bind('drop', function(e) { var droppedFiles = e.dataTransfer.files; // It's as though the following two methods never occur e.stopPropagation(); e.preventDefault(); if (droppedFiles.length &gt; 0) { for (var i=0,ii=droppedFiles.length;i&lt;ii;i++) { $scope.files.push(droppedFiles[i]); } } }); } }; }); </code></pre>

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.
