How can I show all the popovers on a page at the same time?
Assuming your HTML looks like this:
<a href="#" rel="popover" title="My nicer popover text">hover over me</a>
You should set the trigger
option to manual
and show your popovers unconditionally:
$('[rel=popover]').popover({'trigger': 'manual'});
$('[rel=popover]').popover('show');
