    <p>I have added a show more or less function to a div - this all works fine however now i need to only allow this functionality if a element is over a certain height in this case. there are numerous classes of the same so i need to do the check on each element. although i am having problems getting it to work see code below : </p> <pre><code>$(document).ready(function() { $(".less").hide(); $(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight &lt; 150) { $(".more").hide(); } }); $(".more").click(function() { var paragraphHeight = ($(this).parent().parent().find('.appsList').height()); if (paragraphHeight &gt; 150) { $(this).parent().parent().find('.appsHolderBody').animate({height:(paragraphHeight + 100) }); $(this).hide('slow'); $(this).parent().find('.less').show(); } return false; }); $(".less").click(function() { $(this).parent().parent().find('.appsHolderBody').animate({height:190 }); $(this).hide('slow'); $(this).parent().find('.more').show(); return false; }); }); </code></pre> <p>Any help would be greatly appreciated - please note when i am targeting the parent using .parent.parent i know its not pretty but could'nt get it to run using eq(4) for some reason.</p> <p>so the main problem is with this part of code</p> <pre><code>$(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight &lt; 150) { $(".more").hide(); } </code></pre> <p>it hides all of the elements $(".more") instead of the ones that match the condition.</p> <p>html as requested</p> <pre><code>&lt;div class="appsHolder"&gt; &lt;div class="appsHolderBody"&gt; &lt;h5 class="appTitle"&gt;General Apps&lt;/h5&gt; &lt;ul class="appsList"&gt; &lt;li class="mainAppList"&gt;Resource Manager&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Resource Manager&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;li class="mainAppList"&gt;Yet Another App&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;div class="appsHolderExpander"&gt; &lt;a href="" class="more"&gt;More &lt;img src="/wps/PA_applicationsintros/./img/downArrow.png" /&gt;&lt;/a&gt; &lt;a href="" class="less"&gt;Less &lt;img src="/wps/PA_applicationsintros/./img/upArrow.png" /&gt;&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="appsHolderAdvertising"&gt; &lt;div class="appsHolderBody"&gt; &lt;h5 class="appTitle"&gt;Advertising Apps&lt;/h5&gt; &lt;ul class="appsList"&gt; &lt;li class="mainAppList"&gt;ATEX&lt;/li&gt; &lt;li&gt;&lt;a href=""&gt;Launch&lt;/a&gt; &lt;a href=""&gt;Info&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;div class="appsHolderExpander"&gt; &lt;a href="" class="more"&gt;More &lt;img src="/wps/PA_applicationsintros/./img/downArrow.png" /&gt;&lt;/a&gt; &lt;a href="" class="less"&gt;Less &lt;img src="/wps/PA_applicationsintros/./img/upArrow.png" /&gt;&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>cheers in advance </p>

    2. COYou can use the .parents([selector]) of jQuery to select a specific parent. There's also .closest([selector]) - check out the documentation, it explains both: http://api.jquery.com/closest/

Querying!

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).
