Recently I use it on a website for my client. I wrote the following code for my Popover:
<a rel="popover" data-placement="bottom" data-trigger="hover" data-content="Let us see what is inside..." data-original-title="Tips" href="my_link_goes_here"> All Products </a>
Lastly, Popover is triggered using the following jQuery code:
In my HTML mark, I used data-trigger=”hover” to show popover on cursor hover. There are four options for “data-trigger”: click, hover, focus, and manual.
Hope this helps!
