    <p>I did a statistical analysis of <code>.bind()</code> vs <code>.live()</code> vs <code>.delegate()</code> using FF profiler. I did 10 rounds of each (not a sufficient sample to be definitive, but illustrates the point). These are the results.</p> <p>1) Single static element with an id using the click event:</p> <pre><code>.bind(): Mean = 1.139ms, Variance = 0.1276ms .live(): Mean = 1.344ms, Variance = 0.2403ms .delegate(): Mean = 1.290ms, Variance = 0.4417ms </code></pre> <p>2) Multiple static elements with a common class using the click event:</p> <pre><code>.bind(): Mean = 1.089ms, Variance = 0.1202ms .live(): Mean = 1.559ms, Variance = 0.1777ms .delegate(): Mean = 1.397ms, Variance = 0.3146ms </code></pre> <p>3) Multiple dynamic elements (first button creates second...) using the click event:</p> <pre><code>.bind(): Mean = 2.4205ms, Variance = 0.7736ms .live(): Mean = 2.3667ms, Variance = 0.7667ms .delegate(): Mean = 2.1901ms, Variance = 0.2838ms </code></pre> <p>Interpret how you wish, but it seems to me that as dynamic elements increase on a page, .delegate() seems to have the best performance while static elements perform best with .bind().</p> <p>Keep in mind that I am using a very simple click event triggering an alert. Different pages, with different environments (ie. CPU, multi-tab browsing, running threads, etc) will render differing results. I used this as a basic guideline for my decision to use one or the other. Please advise if you have come up with a different result.</p> <p>Thanks!</p>

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.
