    <p>I have a table with this markup:</p> <pre><code>&lt;table&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 3&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 4&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; </code></pre> <p>Every table row is a product and some products have more information. So in this case a table looks like this:</p> <pre><code>&lt;table&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Information 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Information 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 3&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 4&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; </code></pre> <p>I wan't to hide the rows with the product information, and show it after a click on the product row.</p> <p>I tried this with the following Javascript function and onlick="":</p> <pre><code>function showHide(id) { var el = document.getElementById(id); if( el &amp;&amp; el.style.visibility == 'hidden') el.style.visibility = 'visible'; else el.style.visibility = 'hidden'; } </code></pre> <p>But the problem is I don't know how to target only the information rows of the product I've clicked on. It would be easy if I could change the markup, but this markup is generated, so I only can solve it with Javascript.</p> <p>Is ist possible to solve this problem? I have created a fiddle, so it's easier to deliver a quick solution:</p> <p><a href="http://jsfiddle.net/emjay__/8B3M4/" rel="nofollow">http://jsfiddle.net/emjay__/8B3M4/</a></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.
