Just released an update to webapp.data.headIncludes that gets you popovers.
This is what a popover looks like.
Dave, what do you love?
And here's the HTML code for it...
<a href="#" rel="popover" title="I love a parade!" data-content="I love a parade, the tramping of feet, I love every beat I hear of a drum. I love a parade, when I hear a band I just want to stand and cheer as they come. That rat-a tat-tat, the blare of a horn. That rat-a tat-tat, a bright uniform. The sight of a drill will give me a thrill, I thrill at the skill of everything military. I love a parade, a handful of vets, a line of cadets or any brigade, for I love a parade.">what do you love</a>
