    <p>I have the following array of objects which orders the list. The problem is that the ordering is wrong because the OrderId property is not unique across all headings. The OrderId starts from 1 for each heading, hence the problem. Please help! Many thanks</p> <pre><code>// Class var Item = function(orderId, forename, surname, heading) { this.OrderId = orderId; this.Forename = forename; this.Surname = surname; this.Heading = heading; }; // Creation of objects var obj1 = new Item(1, "James", "Smith", "Heading1"); var obj2 = new Item(2, "Tracey", "Janes", "heading1"); var obj3 = new Item(3, "Sarah", "Cann", "Heading1"); var obj4 = new Item(1, "Matt", "Bars", "Heading2"); var obj4 = new Item(2, "Alex", "Magi", "Heading2"); // Add to array tempArray.push(obj1); tempArray.push(obj2); tempArray.push(obj3); tempArray.push(obj4); // Sort array tempArray.sort(function(a, b) { var a1 = a.OrderId, b1 = b.OrderId; if (a1 == b1) return 0; return a1 &gt; b1 ? 1 : -1; }); // Render array to screen - order by OrderId for(var i = 0; i &lt; tempArray.length; i++) { console.log(tempArray[i].Heading); console.log(tempArray[i].Forename + " " + tempArray[i].Surname); } </code></pre> <p><strong>The output I need:</strong></p> <pre><code>Heading 1 James Smith Tracey Janes Sarah Cann Heading 2 Matt Bars Alex Magi </code></pre> <p>Because the OrderId is not unique across I get the following issue</p> <pre><code>Heading 1 James Smith Matt Bars Alex Magi Tracey Janes Sarah Cann Heading 2 </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.

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