    <p>You could do this various different ways. It could be a subtle as a small status on the page saying "Loading...", or as loud as an entire element graying out the page while the new data is loading. The approach I'm taking below will show you how to accomplish both methods.</p> <h3>The Setup</h3> <p>Let's start by getting us a nice "loading" animation from <a href="http://ajaxload.info" rel="noreferrer">http://ajaxload.info</a> I'll be using <img src="https://i.stack.imgur.com/FhHRx.gif" alt="enter image description here"> </p> <p>Let's create an element that we can show/hide anytime we're making an ajax request:</p> <pre><code>&lt;div class="modal"&gt;&lt;!-- Place at bottom of page --&gt;&lt;/div&gt; </code></pre> <h3>The CSS</h3> <p>Next let's give it some flair:</p> <pre><code>/* Start by setting display:none to make this hidden. Then we position it in relation to the viewport window with position:fixed. Width, height, top and left speak for themselves. Background we set to 80% white with our animation centered, and no-repeating */ .modal { display: none; position: fixed; z-index: 1000; top: 0; left: 0; height: 100%; width: 100%; background: rgba( 255, 255, 255, .8 ) url('http://i.stack.imgur.com/FhHRx.gif') 50% 50% no-repeat; } /* When the body has the loading class, we turn the scrollbar off with overflow:hidden */ body.loading .modal { overflow: hidden; } /* Anytime the body has the loading class, our modal element will be visible */ body.loading .modal { display: block; } </code></pre> <h3>And finally, the jQuery</h3> <p>Alright, on to the jQuery. This next part is actually really simple:</p> <pre><code>$body = $("body"); $(document).on({ ajaxStart: function() { $body.addClass("loading"); }, ajaxStop: function() { $body.removeClass("loading"); } }); </code></pre> <p>That's it! We're attaching some events to the body element anytime the <code>ajaxStart</code> or <code>ajaxStop</code> events are fired. When an ajax event starts, we add the "loading" class to the body. and when events are done, we remove the "loading" class from the body.</p> <p>See it in action: <a href="http://jsfiddle.net/VpDUG/4952/" rel="noreferrer">http://jsfiddle.net/VpDUG/4952/</a></p>

    1. COThis is the most in depth solution although I'd recommend you use a centering plugin which centers the preloader around a page element (*i.e. body, #element, or .element*)

    2. COThat would be a nice addition, cballou. I was merely trying to keep the information minimized - but as you point out, it certainly can be improved upon.

    3. COInstead of using an additional div, it's also worth noting you can just make a class for one of the elements that is near the location you want to display the image, and use the same technique, sans an extra div.

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.
