    <p>I'm experimenting with TreeView plug-in located here: <a href="http://docs.jquery.com/Plugins/Treeview" rel="nofollow noreferrer">http://docs.jquery.com/Plugins/Treeview</a></p> <p>One of the options it has is "unique" - to have only one item expanded at a time.</p> <p>It works very well for display purposes, but then I try to hook in to the TreeView's "toggle" property/event to find out which one exactly was expanded.</p> <p>When "unique" is set to true, the function passed to "toggle" seems to get fired for each of the main list elements, preventing me from capturing which one actually initialized expansion. I see why that's done - to make sure other elements are toggled so only one is expanded.</p> <p>Any ideas on how get only the id of the "unique" list item that was toggled/expanded.</p> <p>example code below</p> <pre><code>$(document).ready(function() { $("#browser").treeview({ collapsed: true, unique: true, toggle: function() { $('#console').append(this.id + ' was toggled'); } }); }); &lt;ul&gt; &lt;li id="1"&gt;Ottawa &lt;ul&gt; &lt;li&gt;Item 1&lt;/li&gt; &lt;li&gt;Item 9&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li id="2"&gt;Montreal &lt;ul&gt; &lt;li&gt;Item 2&lt;/li&gt; &lt;li&gt;Item 8&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li id="3"&gt;Quebeque &lt;ul&gt; &lt;li&gt;Item 3&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li id="4"&gt;Calgary &lt;ul&gt; &lt;li&gt;Item 7&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li id="6"&gt;Toronto &lt;ul&gt; &lt;li&gt;Item 10&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;div id="console"&gt;&lt;/div&gt; </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.
