    <p>I am building a dynamic filtering navigation bar for use with the isotope items in my document. I have a few different categories in my nav, each with relative subcategories. I am trying to build a nav where the Main categories show on load. </p> <p>On load I also populate the DOM with all of the elements in random order. When you click a category link it filters out the results, and organizes the relative elements. I also want to show the relative subcategories to the filtered section. Then if you select a different category, the existing subnav fades out, and the relative sub nav fades in.</p> <p>All of my sorting and everything relative to isotope works great. Its the intelligent show/hide of the subnav I am having a hard time with.</p> <p>My HTML:</p> <pre><code>&lt;nav id="filters"&gt; &lt;div id="categories"&gt; &lt;h2&gt;Select a Category:&lt;/h2&gt; &lt;br&gt; &lt;li&gt;&lt;a href="#" data-filter="*"&gt;All Categories&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".autos" data-category="autos"&gt;Autos&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".lifestyle" data-category="lifestyle"&gt;Lifestyle&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".people" data-category="people"&gt;People&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".tech" data-category="tech"&gt;Tech&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".trends" data-category="trends"&gt;Trends&lt;/a&gt;&lt;/li&gt; &lt;br&gt; &lt;/div&gt; &lt;div id="autos"&gt; &lt;h2&gt;Autos:&lt;/h2&gt; &lt;li&gt;&lt;a href="#" data-filter=".autos" data-category="autos"&gt;Show All&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".news" data-category="autos"&gt;News&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".car-tech" data-category="autos"&gt;Car Tech&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".fuel-economy-and-safety" data-category="autos"&gt;Fuel Economy &amp;amp; Safety&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".buying-and-selling" data-category="autos"&gt;Buying &amp;amp; Selling&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".autos, .everything-else" data-category="autos"&gt;Everything Else&lt;/a&gt;&lt;/li&gt; &lt;br&gt; &lt;/div&gt; &lt;div id="lifestyle"&gt; &lt;h2&gt;Lifestyle:&lt;/h2&gt; &lt;li&gt;&lt;a href="#" data-filter=".lifestyle" data-category="lifestyle"&gt;Show All&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".travel" data-category="lifestyle"&gt;Travel&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".music" data-category="lifestyle"&gt;Music&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".food" data-category="lifestyle"&gt;Food&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".shopping" data-category="lifestyle"&gt;Shopping&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".lifestyle, .everything-else" data-category="lifestyle"&gt;Everything Else&lt;/a&gt;&lt;/li&gt; &lt;br&gt; &lt;/div&gt; &lt;div id="people"&gt; &lt;h2&gt;People:&lt;/h2&gt; &lt;li&gt;&lt;a href="#" data-filter=".people" data-category="people"&gt;Show All&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".who-you-know" data-category="people"&gt;Who You Know&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".who-you-should-know" data-category="people"&gt;Who You Should Know&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".people, .everyone-else" data-category="people"&gt;Everyone Else&lt;/a&gt;&lt;/li&gt; &lt;br&gt; &lt;/div&gt; &lt;div id="tech"&gt; &lt;h2&gt;Tech:&lt;/h2&gt; &lt;li&gt;&lt;a href="#" data-filter=".tech" data-category="tech"&gt;Show All&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".business" data-category="tech"&gt;Business&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".pleasure" data-category="tech"&gt;Pleasure&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".tech, .everything-else" data-category="tech"&gt;Everything Else&lt;/a&gt;&lt;/li&gt; &lt;br&gt; &lt;/div&gt; &lt;div id="trends"&gt; &lt;h2&gt;Trends:&lt;/h2&gt; &lt;li&gt;&lt;a href="#" data-filter=".trends" data-category="trends"&gt;Show All&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".online" data-category="trends"&gt;Online&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".offline" data-category="trends"&gt;Offline&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#" data-filter=".trends, .everything-else" data-category="trends"&gt;Everything Else&lt;/a&gt;&lt;/li&gt; &lt;/div&gt; &lt;/nav&gt; </code></pre> <p>My jQuery:</p> <pre><code>$(document).ready(function() { $('#filters &gt; div:gt(0)').hide(); $('#filters a').click(function(){ var selector = $(this).attr('data-filter'); var category = $(this).attr('data-category'); var $subnav = $('#filters').find('#'+category); if($subnav.is(":hidden")) { $subnav.fadeIn(); } if($subnav.is(":visible") &amp;&amp; $subnav.attr("id") != category) { } $container.isotope({ filter: selector }); return false; }); }); </code></pre> <p>I am open to any suggestions. Whether it is restructuring my nav, or redaclaring my variables in a new fashion. I have been staring at this block of code for a while, and brain is turning to mush. I was trying to use the second <code>if</code> statement to handle the hiding of the non-relative subnav.</p> <p>If you like you can hop over to my site with the example on display:</p> <p><a href="http://preview.robabby.com/" rel="nofollow">EXAMPLE</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.
