    <p>This will split your array into 2 arrays:</p> <pre><code>var articles = ["article1", "article2", "article3", "article4", "article5", "article6", "article7", "article8", "article9", "article10"]; var separatorIndex = articles.length &amp; 0x1 ? (articles.length+1)/2 : articles.length/2; var firstChunk = articles.slice(0,separatorIndex); //["article1", "article2", "article3", "article4", "article5"] var secondChunk = articles.slice(separatorIndex,articles.length); //["article6", "article7", "article8", "article9", "article10"] </code></pre> <p>Then you can use them where and/or how you want.</p> <p><em>Explanation</em></p> <p>The 2nd line finds an <em>anchor index</em> (alias -> middle index of division),by which array should be divided into 2 chunks. The array can have <code>odd</code> and <code>even</code> lengths,and those 2 situations must be distinguished. As it is impossible to divide odd-length array into 2 <em>equal</em> parts, it must be divided in such way, that 1st chunk will have 1 element <em>more</em> or <em>less</em>,than 2nd chunk.Here, I have implemented first case,that is, 1st chunk will have 1 element more,than 2nd one. Here are the examples of different situations:</p> <pre><code>total length | 1st (length) | 2st (length) | separatorIndex 10 0-4 (5) 5-9 (5) 5 11 0-5 (6) 6-10 (5) 6 12 0-5 (6) 0-11 (6) 6 </code></pre> <p>In table, <em><code>number</code>-<code>number</code></em> syntax shows accordingly start and end indexes in array. The division is done by <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/slice" rel="nofollow">.slice()</a> function.</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.
