How do you disable the title in Twitter Bootstrap's popover plugin?

baptme's suggest is ok, but the better way would be to specify your popover's title and actually hide it completely as margins still exist with a height of 0.

.popover-title { display: none; }

Edit: just quicky looked at the source and there seems to be an undocumented option:

$.fn.popover.defaults = $.extend({} , $.fn.tooltip.defaults, {
    placement: 'right'
  , content: ''
  , template: '<div class="popover"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
  })

When you declare your popover using JS, try to override the template and specify a hidden title.

$('#example').popover({
    template: '...<h3 class="popover-title" style="display: none"></h3>...'
});

The reason I say don't remove it is it may cause runtime errors if the element doesn't exist. See Sherbrow's comment.

In Bootstrap 2.3+ the title automatically hides if empty.

I wound up using a combination of the techniques suggested by @Terry and @Sherbow. Shows the image, but not the title (for this popup only).

<a href="#" id="contributors" rel="popover">contributors</a>

...

<script>
var contributor_img = '<img src="my_img/contributor.png" />'


$(function ()
{ $('#contributors').popover({ 
    content: contributor_img, 
    template: '<div class="popover"><div class="arrow"></div><div class="popover-inner"><div class="popover-content"><p></p></div></div></div>' });
});
</script>
