popover feature request

Created by: lookfirst

popover is great.

I generally have an image, which is a help icon and then I have a div associated to that icon which I want to display the contents of, as html, within the popover.

It'd be a million times more useful for me if I could do this:

<img class="helpIcon" src="/img/help22.png" width="16" height="16" title="Help!" data-divId="helpContent" />
<div id="helpContent" style="display: none;">
    <h2>my help content here</h2>
</div>

Then, I could just install one jquery handler for all .helpIcon's.

Maybe it already does this and I'm missing it? Just making data-content="#myid" work would be acceptable too.
