    <p>To all jQuery heros out there, I need help! (again) </p> <p>I found similar questions to mine on the internet but there were no answers so far :-/</p> <p>I want to filter a bunch of items with jquery isotope. I adapted the combination filter example from the plugin homepage, which works fine and looks like so: </p> <pre><code>$(function () { var $container = $('#container'), filters = {}; $container.isotope({ itemSelector: '.item', filter: '', }); // filter links $('.filter a').click(function () { var $this = $(this); // don't proceed if already selected if ($this.hasClass('selected')) { return; } var $optionSet = $this.parents('.option-set'); // change selected class $optionSet.find('.selected').removeClass('selected'); $this.addClass('selected'); // store filter value in object // i.e. filters.color = 'red' var group = $optionSet.attr('data-filter-group'); filters[group] = $this.attr('data-filter-value'); // convert object into array var isoFilters = []; for (var prop in filters) { isoFilters.push(filters[prop]) } var selector = isoFilters.join(''); $container.isotope({ filter: selector }); return false; }); }); </code></pre> <p>and some html of the filter menu:</p> <pre><code>&lt;div id="nav"&gt; &lt;ul class="filter option-set" data-filter-group="who"&gt; &lt;li&gt;&lt;a href="#filter-who-any" data-filter-value="" class="selected"&gt;Any&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#filter-who-boys" data-filter-value=".boys"&gt;Boys&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#filter-who-girls" data-filter-value=".girls"&gt;Girls&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p>I set up a fiddle demo with 3 filter categories which can be combined: <strong><a href="http://jsfiddle.net/alani/XERHK/" rel="nofollow">jsFiddle</a></strong></p> <p>Now I'd like to make it possible to select <strong>multiple</strong> tags from each category:</p> <p>Category 1: a <strong>OR</strong> b <strong>OR</strong> c</p> <p><strong>AND</strong></p> <p>Categoy 2: a <strong>OR</strong> b <strong>OR</strong> c</p> <p><strong>AND</strong></p> <p>Categoy 3: a <strong>OR</strong> b <strong>OR</strong> c</p> <p>There's a <a href="http://jsfiddle.net/desandro/GwBa8/" rel="nofollow">check-box-example</a> by desandro, but this is not quite the thing I'm searching for, because I want to keep the AND condition between the categories. Basically I want 3 filter categories with some check-boxes for each of them (or links but I guess check-boxes are more functional). I think the methods used in both examples are completely different and I don't know how to combine their functionality. </p> <p>I hope you get my point and that anyone could help me find a solution. </p> <p>Thanks in advance!</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.
