    <p>I have a table displaying some information. What I'd like to accomplish is to allow the user to click on a row, and have the note related to the info in that row display below that row.</p> <p>I am trying to set it up so that I can use the nifty CSS transition feature, so just putting the note in a hidden, absolutely positioned row below the info row is out of the question. CSS transition doesn't act on the <code>position</code> style.</p> <p>I've got it set up so that the note will be in a <code>div</code>. When the user clicks a row in the table, an <code>onClick</code> event calls up a Javascript function which makes the <code>div</code> visible. Now all I need is for the div to line up under the selected table row.</p> <p>How could I get the table row's height and position? I figure I could use that to position the <code>div</code>. Or, is there a better way to do this?</p> <p>Here's an example of what I've got:</p> <pre><code>&lt;style&gt; .emarNote{ transition: all .3s linear; -o-transition: all .3s linear; -moz-transition: all .3s linear; -webkit-transition: all .3s linear; } &lt;/style&gt; &lt;script type="text/javascript"&gt; function showEmar(id) { if (document.getElementById("emarNote"+id).style.visibility == "hidden") { document.getElementById("emarNote"+id).style.visibility = 'visible'; document.getElementById("emarNote"+id).style.opacity = 1; } else { document.getElementById("emarNote"+id).style.opacity = 0; document.getElementById("emarNote"+id).style.visibility = 'hidden'; } } &lt;/script&gt; &lt;table&gt; &lt;tr onClick="showEmar(1)"&gt; &lt;td&gt;Info&lt;/td&gt; &lt;td&gt;Info&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;div id="emar1" class="emarNote" style="visibility:hidden; opacity:0; position:absolute;"&gt; note about info &lt;/div&gt; </code></pre>

    1. COAre you allowed to use jQuery in this project? That would probably be the easiest (though not necessarily *best*) way to accomplish your goal. Reliably calculating height/width in a cross-browser way is a non-trivial task w/o a JS library to do it for you.

    2. COjQuery would be fine. I have sadly yet to learn much about it, so any new exposure would be helpful.

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.
