    <p>Here's what I came up with in the end.</p> <pre><code>// here's our active element. var $active = $('#active'); // here is the filter we'll be testing against. var filter = "img.a"; // $all will be the final jQuery object with all the consecutively matched elements. // start it out by populating it with the current object. var $all = $active; for ($curr = $active.prev(filter); $curr.length &gt; 0; $curr = $curr.prev(filter)) { $all = $all.add($curr); } for ($curr = $td.next(filter); $curr.length &gt; 0; $curr = $curr.next(filter)) { $all = $all.add($curr); } </code></pre> <p>For a follow up question, I could see how this could easily be generalised by making it into a function which takes two arguments: an initial element, and a filter string - can anyone point me in the right direction to find out how to extend the jQuery object to add such a function?</p> <hr> <p><strong>Edit</strong>: I've since found that the each() function would do this rather well for some purposes. In my own case it doesn't work as cleanly, since I want a single jQuery object for all those elements, but here's how you could use each for a different purpose (hiding consecutive ".a" elements, in this example:)</p> <pre><code>$('#active') .nextAll() .each(hideConsecutive) .end() .prevAll() .each(hideConsecutive) ; function hideConsecutive(index, element) { var $e = $(element); if (!$e.is(".a")) { return false; // this stops the each function. } else { $e.hide('slow'); } } </code></pre> <p>--</p> <p>Edit: I've put this together into a plugin now. Take a look at <a href="http://plugins.jquery.com/project/Adjacent" rel="nofollow noreferrer">http://plugins.jquery.com/project/Adjacent</a> if you're interested.</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.
