    <h1>Updated <a href="http://jsfiddle.net/gvee/Qq247/4/" rel="nofollow">JSFiddle</a></h1> <p>Rather than trying to delay animations and work our timings etc you can simply set a function call to happen when your animation step is complete.</p> <p>The <code>animate()</code> function optionally accepts extra parameters. From <a href="http://api.jquery.com/animate/#animate-properties-duration-easing-complete" rel="nofollow">the manual</a>:</p> <blockquote> <p><strong>.animate( properties [, duration ] [, easing ] [, complete ] )</strong></p> <p>...</p> <blockquote> <p><strong>complete</strong></p> <p>Type: <a href="http://api.jquery.com/Types#Function" rel="nofollow">Function()</a></p> <p>A function to call once the animation is complete.</p> </blockquote> </blockquote> <p>This means you can call a function when your animation is complete. Here's a simple example:</p> <pre><code>$('div').click(function() { $(this).animate({width: 200}, 5000, function() { alert('animation complete'); }); }); </code></pre> <p>In the above code we are popping up a message after the initial animation (width: 200px) is complete.</p> <p>So how is this useful to you? Well, what if we call our second animation once the first has completed, and the 3rd after that had completed, and so on?</p> <pre><code>$('#' + i).animate({width:randomWidth, opacity:'0.3'} , 1000, function() { $(this).animate({height:randomHeight, opacity:'1' }, 1000, function() { $(this).animate({width:'50', opacity:'1'}, 1000, function() { $(this).animate( {height:newHeight, opacity:'1' }, 1000); }); }); }); </code></pre> <p><strong>EDIT:</strong> Here's your code after refactoring:</p> <pre><code>function letsGo(i, newHeight) { var randomWidth = Math.floor(Math.random() * 201 + 50); var randomHeight = Math.floor(Math.random() * 201 + 50); $('#' + i).animate({width:randomWidth, opacity:'0.3'} , 1000, function() { $(this).animate({height:randomHeight, opacity:'1' }, 1000, function() { $(this).animate({width:'50', opacity:'1'}, 1000, function() { $(this).animate( {height:newHeight, opacity:'1' }, 1000); }); }); }); } $('.items').click(function () { var newHeight = 50; var divCount = $('.items').length; for(i=1; i&lt;=divCount; i++) { letsGo(i, newHeight); newHeight += 50; }; }); </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.
