HTML inside Twitter Bootstrap popover

You cannot use <li href="#" since it belongs to <a href="#" that’s why it wasn’t working, change it and it’s all good.

Here is working JSFiddle which shows you how to create bootstrap popover.

Relevant parts of the code is below:

HTML:

<!-- 
Note: Popover content is read from "data-content" and "title" tags.
-->
<a tabindex="0"
   class="btn btn-lg btn-primary" 
   role="button" 
   data-html="true" 
   data-toggle="popover" 
   data-trigger="focus" 
   title="<b>Example popover</b> - title" 
   data-content="<div><b>Example popover</b> - content</div>">Example popover</a>

JavaScript:

$(function(){
    // Enables popover
    $("[data-toggle=popover]").popover();
});

And by the way, you always need at least $("[data-toggle=popover]").popover(); to enable the popover. But in place of data-toggle="popover" you can also use id="my-popover" or class="my-popover". Just remember to enable them using e.g: $("#my-popover").popover(); in those cases.

Bonus:

If for some reason you don’t like or cannot read content of a popup from the data-content and title tags. You can also use e.g. hidden divs and a bit more JavaScript. Here is an example about that.
