    <p>Here's my situation. I have a sliding jquery menu like this: <a href="http://tympanus.net/codrops/2011/07/03/sliding-background-image-menu" rel="nofollow">http://tympanus.net/codrops/2011/07/03/sliding-background-image-menu</a>.</p> <p>The code of menu is:</p> <pre><code>&lt;div id="sbi_container" class="sbi_container"&gt; &lt;div class="sbi_panel" data-bg="images/1.jpg"&gt; &lt;a href="#" class="sbi_label"&gt;About&lt;/a&gt; &lt;div class="sbi_content"&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;Subitem&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Subitem&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Subitem&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="sbi_panel" data-bg="images/2.jpg"&gt; ... &lt;/div&gt; </code></pre> <p>CSS:</p> <pre><code>.sbi_content{ position:absolute; border-top:2px solid #000; bottom:90px; left:0px; width:100%; background:transparent url(../images/pattern.png) repeat top left; display:none; overflow:hidden; } .sbi_content ul{ padding:10px; } .sbi_content ul a{ display:block; color:#f0f0f0; font-size:16px; padding:4px 6px 4px 14px; background:transparent url(../images/triangle.png) no-repeat 3px 50%; opacity:0.9; } .sbi_content ul a:hover{ background-color:#000; color:#fff; -moz-box-shadow:1px 1px 5px #000; -webkit-box-shadow:1px 1px 5px #000; box-shadow:1px 1px 5px #000; } </code></pre> <p>And here's a JavaScript piece I have a problem with: </p> <pre><code> $content.each(function(i) { var $el = $(this); // save each content's height (where the menu items are) // and hide them by setting the height to 0px var num = $el.find('ul li').size(); $el.data( 'height', num * 35 + 10 ).css( 'height', '0px' ).show(); }); </code></pre> <p>I need to count a height of these <code>&lt;ul&gt;</code>. That I'm doing now is counting how many there are <code>&lt;li&gt;</code> items, then multiply it by number of one's height (35) and adding a 10px for margin..</p> <p>Everything would be ok, but when there is a realy long <code>&lt;li&gt;</code> item, it jumps to second row and problem is that this code doesn't count that second row height.</p> <p>Any ideas how can I solve this problem?</p> <p>Thank you.</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.

SQuiL has stopped working due to an internal error.

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