    <p><strong>Example HTML</strong> (for the sake of clarity):</p> <pre><code>&lt;nav&gt; &lt;ul&gt; &lt;li class="top-navbar-channels"&gt; &lt;a href="#"&gt;&lt;/a&gt; &lt;div class="dropdown-menu"&gt;BLAH, BLAH, BLAH!&lt;/div&gt; &lt;/li&gt; &lt;li class="top-navbar-about"&gt; &lt;a href="#"&gt;&lt;/a&gt; &lt;div class="dropdown-menu-about"&gt;BLAH, BLAH, BLAH!&lt;/div&gt; &lt;/li&gt; &lt;li class="top-navbar-search"&gt; &lt;a href="#"&gt;&lt;/a&gt; &lt;div class="dropdown-menu-search"&gt;BLAH, BLAH, BLAH!&lt;/div&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/nav&gt; </code></pre> <p><strong>Example jQuery code:</strong></p> <pre><code>jQuery(document).ready(function($){ $('.dropdown-menu').on('show', function () { $('.top-navbar-channels &gt; a').addClass('selected'); }); $('.dropdown-menu').on('hide', function () { $('.top-navbar-channels &gt; a').removeClass('selected'); }); $('.dropdown-menu-about').on('show', function () { $('.top-navbar-about &gt; a').addClass('selected'); }); $('.dropdown-menu-about').on('hide', function () { $('.top-navbar-about &gt; a').removeClass('selected'); }); $('.dropdown-menu-search').on('show', function () { $('.top-navbar-search &gt; a').addClass('selected'); }); $('.dropdown-menu-search').on('hide', function () { $('.top-navbar-search &gt; a').removeClass('selected'); }); }); </code></pre> <p><strong>For those who are curious...</strong> the jQuery code adds a new class <code>selected</code> to the active menu item's link. In my case it's <a href="http://twitter.github.com/bootstrap/javascript.html#collapse" rel="nofollow">Twitter Bootstrap-based collapsible menu</a>, where active means, the menu item is not collapsed i.e. open.</p> <p>Now, the question is, can the jQuery code be optimized (i.e. same functionality with less code)? If so, how?</p>

    2. CO@Adil All menus (`li`) are horizontally placed using `float` CSS property. The first menu is floated `left` white the other two are floated `right`, and hence the change in order. Anyway, since it's unnecessary, I edit the code and remove the complexity. ;) **EDIT:** Or were you referring to something else?

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).
