    <p>I am coding a webpage to be viewed on iPad. It uses Safaris/Webkits drag &amp; drop. I have exactly copied Safari's example drag &amp; drop code but it won't work.</p> <p><strong>My Problem:</strong> The ondrop event is never triggered when I run the webpage (HTML, CSS &amp; Javascript) on Safari Desktop or on Safari on an iPad. On ipad I cannot even drag the elements (the microscope thingie appears &amp; it won't drag when I hold &amp; move my finger over the element). The drag does work on desktop though.</p> <p>What's going wrong?</p> <p>The small code example can be found at the very bottom of this page: <a href="https://developer.apple.com/library/archive/documentation/AppleApplications/Conceptual/SafariJSProgTopics/DragAndDrop.html" rel="nofollow noreferrer">https://developer.apple.com/library/archive/documentation/AppleApplications/Conceptual/SafariJSProgTopics/DragAndDrop.html</a></p> <p><div class="snippet" data-lang="js" data-hide="true" data-console="false" data-babel="false"> <div class="snippet-code snippet-currently-hidden"> <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;Drag-and-Drop&lt;/title&gt; &lt;script&gt; &lt;!-- var dragitem = undefined; function setdragitem(item, evt) { dragitem = item; // alert('item: '+item); // item is an HTML DIV element. // evt is an event. // If the item should not be draggable, enable this next line. // evt.preventDefault(); return true; } function cleardragitem() { dragitem = undefined; // alert('item: '+item); } function dodrag() { // alert('item: '+dragitem); } // This is required---used to tell WebKit that the drag should // be allowed. function handledragenter(elt, evt) { evt.preventDefault(); return true; } function handledragover(elt, evt) { evt.preventDefault(); return true; } function handledragleave(elt, evt) { } function handledrop(elt, evt) { // alert('drop'); dragitem.style.display = "none"; var newid = dragitem.id + '_dest'; var dest = document.getElementById(newid); dest.innerHTML = dragitem.innerHTML; } // --&gt; &lt;/script&gt; &lt;style&gt; &lt;!-- .wordbox { border: 1px solid black; text-align: center; width: 50px; float: left; -webkit-user-drag: element; -webkit-user-select: none; } .spacer { clear: both; } .target { margin-top: 30px; padding: 30px; width: 70px; border: 1px solid black; background: #c0c0ff; margin-bottom: 30px; -webkit-user-drop: element; } .word { margin: 30px; min-height: 30px; border-bottom: 1px solid black; width: 50px; float: left; } --&gt; &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;p&gt;Drop words onto target area to put them in their places.&lt;/p&gt; &lt;div class='wordbox' id='this' ondragstart='setdragitem(this, event);' ondrag='dodrag();' ondragend='cleardragitem();'&gt;This&lt;/div&gt; &lt;div class='wordbox' id='is' ondragstart='setdragitem(this, event);' ondrag='dodrag();' ondragend='cleardragitem();'&gt;is&lt;/div&gt; &lt;div class='wordbox' id='a' ondragstart='setdragitem(this, event);' ondrag='dodrag();' ondragend='cleardragitem();'&gt;a&lt;/div&gt; &lt;div class='wordbox' id='test' ondragstart='setdragitem(this, event);' ondrag='dodrag();' ondragend='cleardragitem();'&gt;test&lt;/div&gt; &lt;div class='spacer'&gt;&lt;/div&gt; &lt;div class='target' ondragenter='handledragenter(this, event);' ondragover='handledragover(this, event);' ondragleave='handledragleave(this, event);' ondrop='handledrop(this, event);'&gt;TARGET&lt;/div&gt; &lt;div class='words'&gt; &lt;div class='word' id='this_dest'&gt;&lt;/div&gt; &lt;div class='word' id='is_dest'&gt;&lt;/div&gt; &lt;div class='word' id='a_dest'&gt;&lt;/div&gt; &lt;div class='word' id='test_dest'&gt;&lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt;</code></pre> </div> </div> </p> <p><strong>Here is the JSFiddle</strong> (remember the drag &amp; drop is Webkit so only for Safari-this webpage is for ipad only): <a href="https://jsfiddle.net/eyM3y/" rel="nofollow noreferrer">https://jsfiddle.net/eyM3y/</a></p>

    1. COi don't get your problem. I have just tested with Chrome (16.0.912.75) Safari (5.1.2 (7534.52.7)), and my iPad running iOS 5.0.1 and it works fine, handledrop is called. What is missing that I can't reproduce this?

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.

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