    <p>Here's my handy dandy line of code:</p> <pre><code>$('#options th.subhead').each(function(){$(this).parents('table').find('td:nth-child('+$(this).prevAll().length+')').andSelf().toggle();}); </code></pre> <p>Now... in theory, I thought that what this should do was take any th with class "subhead" in the table id'd as options and go find any td of the same column and toggle it. Oh, as well as the original th.</p> <p>Guess what. It wipes out and returns the whole contents of the table.</p> <p>I'm missing something here. Is "this" where I'm doing preVall and length no longer the this I'm thinking of?</p> <p>Update! wirey got my closer with his comment.</p> <p>I'm here now:</p> <pre><code>$('#options th.subhead').each(function(){$(this).parents('table').find('td:nth-child('+$(this).prevAll().length+')').toggle();}).toggle(); </code></pre> <p>This works great EXCEPT that it is hiding the wrong td's. It seems to be one column over on the first one, correct on the next two and one column to the left on the last one. LOL</p> <p>UPDATE 2.5 (due to bad url):</p> <p>I made a fiddle <a href="http://jsfiddle.net/MatthewDavis/8nTXB/1/" rel="nofollow">http://jsfiddle.net/MatthewDavis/8nTXB/1/</a></p> <p>UPDATE 3 Got it thanks to wirey. Here's the final fiddle! <a href="http://jsfiddle.net/MatthewDavis/8nTXB/2/" rel="nofollow">http://jsfiddle.net/MatthewDavis/8nTXB/2/</a></p> <p>And the completed line of code.</p> <pre><code>$('#options th.subhead').each(function () { $(this).parents('table').find('td:nth-child(' + ($(this).prevAll().length+1) + ')').toggle(); }).toggle(); </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.
