Is it possible to use a div as content for Twitter's Popover

First of all, if you want to use HTML inside the content you need to set the HTML option to true:

$('.danger').popover({ html : true});

Then you have two options to set the content for a Popover

• Use the data-content attribute. This is the default option.
• Use a custom JS function which returns the HTML content.

Using data-content: You need to escape the HTML content, something like this:

<a class='danger' data-placement='above' 
   data-content="&lt;div&gt;This is your div content&lt;/div&gt;" 
   title="Title" href='#'>Click</a>

You can either escape the HTML manually or use a function. I don't know about PHP but in Rails we use *html_safe*.

Using a JS function: If you do this, you have several options. The easiest I think is to put your div content hidden wherever you want and then write a function to pass its content to popover. Something like this:

$(document).ready(function(){
  $('.danger').popover({ 
    html : true,
    content: function() {
      return $('#popover_content_wrapper').html();
    }
  });
});

And then your HTML looks like this:

<a class='danger' data-placement='above' title="Popover Title" href='#'>Click</a>
<div id="popover_content_wrapper" style="display: none">
  <div>This is your div content</div>
</div>

Hope it helps!

PS: I've had some troubles when using popover and not setting the title attribute... so, remember to always set the title.

Building on jävi's answer, this can be done without IDs or additional button attributes like this:

http://jsfiddle.net/isherwood/E5Ly5/

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My first popover content goes here.</div>

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My second popover content goes here.</div>

<button class="popper" data-toggle="popover">Pop me</button>
<div class="popper-content hide">My third popover content goes here.</div>

$('.popper').popover({
    container: 'body',
    html: true,
    content: function () {
        return $(this).next('.popper-content').html();
    }
});

Another alternate method if you wish to just have look and feel of pop over. Following is the method. Offcourse this is a manual thing, but nicely workable :)

HTML - button

<button class="btn btn-info btn-small" style="margin-right:5px;" id="bg" data-placement='bottom' rel="tooltip" title="Background Image"><i class="icon-picture icon-white"></i></button>

HTML - popover

<div class="bgform popover fade bottom in">
            <div class="arrow"></div>
             ..... your code here .......
</div>

JS

$("#bg").click(function(){
        $('.bgform').slideToggle();
});
