    <p>First of all your script doesn't take into account that minimal timeout is usually 10-15ms depending on a browser. You can see <a href="http://lazutkin.com/blog/2008/mar/23/javascript-edp-and-0ms-timeouts/" rel="nofollow noreferrer">my post on this topic</a>. Inside you'll find a table for popular browsers and a link to the program that measures it, so you can verify the claim yourself. I am sorry to say but iterations every 5ms is a wishful thinking.</p> <p>Secondly, timers are not interrupts. There is no magic in them &mdash; they cannot interrupt whatever is running in the browser and execute their payload. Instead they are going to be deferred until the running code finishes and the browser gets back the control and the ability to run timers. Fading 50 elements take time, and I bet it is more than 5ms, especially if you take into account the whole deferred model of the browser: you update DOM, and the browser will update its visual representation &hellip; at some point in time.</p> <p>I want to finish on a positive note:</p> <ul> <li>Instead of fading out 50 individual elements, try to group them and fade their parent &mdash; it can be faster.</li> <li>Be more creative at UI. Try to come up with a solution, which doesn't require fading out a lot of independent elements at once.</li> <li>Always verify that your background assumptions are correct before designing around them.</li> <li>If you can, try to target modern browsers. From my personal experience Google Chrome is very good with timers, and its JavaScript engine (V8) is extremely fast.</li> </ul>

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.
