    <p>I'm trying to get an element to animate to its "natural" height - i.e. the height it would be if it had <code>height: auto;</code>.</p> <p>I've come up with this:</p> <pre><code>var currentHeight = $this.height(); $this.css('height', 'auto'); var height = $this.height(); $this.css('height', currentHeight + 'px'); $this.animate({'height': height}); </code></pre> <p>Is there a better way to do this? It feels like a bit of a hack.</p> <p>Edit: Here's a complete script to play with for anyone that wants to test.</p> <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;title&gt;jQuery&lt;/title&gt; &lt;style type="text/css"&gt; p { overflow: hidden; background-color: red; border: 1px solid black; } .closed { height: 1px; } &lt;/style&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $().ready(function() { $('div').click(function() { $('p').each(function() { var $this = $(this); if ($this.hasClass('closed')) { var currentHeight = $this.height(); $this.css('height', 'auto'); var height = $this.height(); $this.css('height', currentHeight + 'px'); $this.animate({'height': height}); } else { $this.animate({'height': 1}); } $this.toggleClass('closed'); }); }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div&gt;Click Me&lt;/div&gt; &lt;p&gt;Hello - I started open&lt;/p&gt; &lt;p class="closed"&gt;Hello - I started closed&lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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.
