It looks like they have been trying to make that an option, they even have a tooltip-html-unsafe that seems to work for tooltips.
<a popover-placement="bottom" popover-append-to-body="true" popover="<h1>LOG OUT</h1>" tooltip-html-unsafe>BUTTON HERE</a>
Your may be able to work in a popover version, something like this works :
angular.module( 'ui.bootstrap.popover')
.directive( 'popoverHtmlUnsafePopup', function () {
return {
restrict: 'EA',
replace: true,
scope: { content: '@', placement: '@', animation: '&', isOpen: '&' },
templateUrl: 'template/tooltip/tooltip-html-unsafe-popup.html'
};
})
.directive( 'popoverHtmlUnsafe', [ '$tooltip', function ( $tooltip ) {
return $tooltip('popoverHtmlUnsafe', 'popover', 'click' );
}]);
but I would probably just use a dropdown.
