    <p>I see you're using jQuery (and have edited your question accordingly).</p> <p>With jQuery, it's really easy to get a list of matching elements using CSS syntax:</p> <pre><code>var list = $('#parentId &gt; .selected'); </code></pre> <p>That gets a list of the direct children of the element with the ID "parentId" that have the class "selected". You can then do things with them, such as:</p> <pre><code>list.removeClass("selected"); </code></pre> <p>Then add "selected" to the element you want to select.</p> <p><strong>Edit</strong> I think this should do it:</p> <pre><code>$(thumbs).click(function() { // Remove selected class from any elements other than this var clicked, previous; clicked = $(this); if (!clicked.hasClass(clickedClass)) { previous = $(thumbs+'.'+clickedClass); previous.removeClass(clickedClass).fadeTo(fadeTime, inactiveOpacity); clicked.addClass(clickedClass).fadeTo(fadeTime, activeOpacity); } }); </code></pre> <p>I'm assuming there that the "selected" class isn't necessary for the fade effect to look right.</p> <p>Note how the above will completely ignore the click if the clicked element already has the class. If you don't want that, remove the <code>hasClass</code> check and add <code>.not(clicked)</code> to the end of the <code>previous = $(thumbs+'.'+clickedClass)</code> line, but I don't know what your fade in would do at that point if you've already done it once.</p> <p>I'm not getting the hover stuff; I thought you wanted this to happen on click, not hover.</p>

    1. COThis seems most close to what I need, but I can't quite get it to work... could you put it in context in the code above? I tried this: var previous = $(thumbs + '.' + clickedClass).eq(); var list = $('#list li .selected'); var clicked = $(this); if(clicked !== previous) { list.removeClass(clickedClass); } clicked.addClass(clickedClass).fadeTo(fadeTime, activeOpacity); }); but the thumbs still don't fade out after clicking a new one.

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.
