    <p>I want to let users expand thumbnail to see large profile pic on mouseover. However, the rollover effect I have currently expands the table row to the size of the expanded image rather than showing the image over the surrounding text. Can anyone suggest a way to expand images on rollover without moving text around, in other words showing larger image on top of other html rather than pushing it out of way. I have tried z-index and this does not seem to work.</p> <p>Here is a jsfiddle that demonstrates the problem:</p> <p><a href="http://jsfiddle.net/gLr9Q/" rel="nofollow">http://jsfiddle.net/gLr9Q/</a></p> <p>Here is same code as in js fiddle:</p> <p></p> <pre><code>&lt;script language="JavaScript"&gt; &lt;!-- hide from non JavaScript Browsers image = new Array() image[0]= new Image(24,24) image[0].src = "http://womeninbiznetwork.com/wp-content/uploads/2011/07/logo-google.thumbnail.gif" image[1] = new Image(48,48) image[1].src = "https://www.google.com/intl/en_ALL/images/logos/images_logo_lg.gif" &lt;/script&gt; &lt;tr&gt;&lt;td colspan=2&gt; &lt;p align="center"&gt; &lt;a href="contactdetail.php" onmouseover="newPic()" onmouseout="oldPic()"&gt; &lt;img src="http://womeninbiznetwork.com/wp-content/uploads/2011/07/logo-google.thumbnail.gif" name="pic" class="rollover" border=0&gt; &lt;/a&gt; &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;Here is text&lt;/td&gt;&lt;/tr&gt; </code></pre> <p>js</p> <pre><code>function newPic(){ document.pic.style.left="-24px"; document.pic.style.top="-24px"; document.pic.src = image[1].src; return true; } function oldPic(){ document.pic.src = image[0].src; return true; } </code></pre> <p>css:</p> <pre><code>#rollover { display: block; z-index:99; padding: 4px; position:relative; text-align:left; width:48px; background-color:#E8E8E8; opacity:1.0; filter:alpha(opacity=100); } </code></pre>

    1. COYou're probably going to want to clone the element and position it absolutely based on the location of the thumbnail.

    2. CONo need to clone it and it's actually possible with only CSS and :hover. It requires the images container to have a given width and height though.

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.
