    <p>These days with show / hide javascript, I prefer to use HTML5's data-* attributes.</p> <p>This can already be used in non-HTML5 browsers via the getAttribute and setAttribute function.</p> <p>I've quickly tried it against IE7, Chrome and Opera and it seems to work.</p> <p><a href="http://jsfiddle.net/ThJcb/" rel="nofollow">http://jsfiddle.net/ThJcb/</a></p> <pre><code>function showHide(shID) { var exDiv = document.getElementById(shID); if(exDiv.getAttribute("data-visible") != 'false'){ document.getElementById(shID+'-show').style.cssText = ';height:auto;opacity:1;visibility:visible;'; document.getElementById(shID).style.cssText = ';height:0;opacity:0;visibility:hidden;'; exDiv.setAttribute("data-visible" , 'false'); } else { document.getElementById(shID+'-show').style.cssText = ';height:;opacity:0;visibility:hidden;'; document.getElementById(shID).style.cssText = ';height:auto;opacity:1;visibility: visible ;'; exDiv.setAttribute("data-visible" , 'true'); } } </code></pre> <p>This allows you to determine the state of the div without having to check for CSS values.</p> <p><strong>EDIT</strong>: As pointed out in the comments, a typo was on the hide link (onlick instead of onclick) which made it appear the above jsfiddle worked whereas it didn't. At least not exactly as I made an error in the logic, setting the "data-visible" to false instead of true.</p> <p>Here's an updated jsfiddle: <a href="http://jsfiddle.net/ThJcb/4/" rel="nofollow">http://jsfiddle.net/ThJcb/4/</a> (javascript snippet above updated also)</p>

    1. COThe script has the problem of reloading the page when the 'Hide Content' link is clicked, see this updated JSFiddle with a body margin (scroll down to the link, click it to see what I mean): http://jsfiddle.net/ThJcb/1/

    2. COUpdate: The script was reloading the page because the 'Hide Content' link had a 'onlick' not 'onclick' function, which made it seem like the script was working, when in fact it didn't :( See this updated JSFiddle: http://jsfiddle.net/ThJcb/3/

    3. COThank you so much. The code works beautifully in JSFiddle. Unfortunately when I tested it in my HTML it doesn't load. I think it's because in JSFiddle the 'Framework' is set to 'No Wrap (head)' - any suggestions for tweaking it to work with OnLoad?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
