    <p>I have two options that I am trying to filter between now, but will be adding in a third and maybe a fourth later on (for example: right now I am filtering between prices and reviews but will want to add more prices to the list and also another filter category like "rating" which would consist of 3, 4, or 5 stars).</p> <p>Using the logic that I have listed below works fine, but I feel it will get really long and complicated (and unnecessary) as I go. I know there is a way to refactor the code I'm just wondering what the best way to go about it would be? HTML:</p> <pre><code> &lt;select class="deals"&gt; &lt;option value="deals-all"&gt;All deals&lt;/option&gt; &lt;option value="50"&gt;$50&lt;/option&gt; &lt;option value="25"&gt;$25&lt;/option&gt; &lt;/select&gt; &lt;select class="reviews"&gt; &lt;option value="reviews-all"&gt;All reviews&lt;/option&gt; &lt;option value="reviews-positive"&gt;Positive reviews&lt;/option&gt; &lt;option value="reviews-negative"&gt;Negative reviews&lt;/option&gt; &lt;/select&gt; </code></pre> <p>jQuery</p> <pre><code> $('.reviews, .deals').change(function() { var reviewsVal = $('.reviews :selected').val(); var dealsVal = $('.deals :selected').val(); if((reviewsVal == 'reviews-all') &amp;&amp; (dealsVal == 'deals-all')) { $('.review-positive').show(); $('.review-negative').show(); $('.deals-25').show(); $('.deals-50').show(); } else if((dealsVal == '50') &amp;&amp; (reviewsVal == 'reviews-positive')) { $('.review-negative.deals-50').hide(); $('.review-positive.deals-50').show(); $('.review-negative.deals-25').hide(); $('.review-positive.deals-25').hide(); } else if((dealsVal == '50') &amp;&amp; (reviewsVal == 'reviews-negative')) { $('.review-negative.deals-50').show(); $('.review-positive.deals-50').hide(); $('.review-negative.deals-25').hide(); $('.review-positive.deals-25').hide(); } else if((dealsVal == '25') &amp;&amp; (reviewsVal == 'reviews-positive')) { $('.review-negative.deals-50').hide(); $('.review-positive.deals-50').hide(); $('.review-negative.deals-25').hide(); $('.review-positive.deals-25').show(); } else if((dealsVal == '25') &amp;&amp; (reviewsVal == 'reviews-negative')) { $('.review-negative.deals-50').hide(); $('.review-positive.deals-50').hide(); $('.review-negative.deals-25').show(); $('.review-positive.deals-25').hide(); } else if((dealsVal == 'deals-all') &amp;&amp; (reviewsVal == 'reviews-positive')) { $('.review-negative.deals-50').hide(); $('.review-positive.deals-50').show(); $('.review-negative.deals-25').hide(); $('.review-positive.deals-25').show(); } else if((dealsVal == 'deals-all') &amp;&amp; (reviewsVal == 'reviews-negative')) { $('.review-negative.deals-50').show(); $('.review-positive.deals-50').hide(); $('.review-negative.deals-25').show(); $('.review-positive.deals-25').hide(); } else if((dealsVal == '50') &amp;&amp; (reviewsVal == 'reviews-all')) { $('.review-negative.deals-50').show(); $('.review-positive.deals-50').show(); $('.review-negative.deals-25').hide(); $('.review-positive.deals-25').hide(); } else if((dealsVal == '25') &amp;&amp; (reviewsVal == 'reviews-all')) { $('.review-negative.deals-50').hide(); $('.review-positive.deals-50').hide(); $('.review-negative.deals-25').show(); $('.review-positive.deals-25').show(); } else { $('.review-positive').show(); $('.review-negative').show(); $('.deals-25').show(); $('.deals-50').show(); } }); $('.reviews-positive').click(function() { $('.review-negative').hide(); $('.review-positive').show(); }); $('.reviews-negative').click(function() { $('.review-positive').hide(); $('.review-negative').show(); }); });​ </code></pre> <p>Hopefully you can see what I am going for, thanks for any input.</p> <p>*EDIT: jsfiddle: <a href="http://jsfiddle.net/TXywp/1/" rel="nofollow">http://jsfiddle.net/TXywp/1/</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
