This question already has an answer here:
Is it possible to show a tooltip in Twitter Bootstrap that uses html tags in it to give it some mark-up?
At the moment I'm using this code:
<a class="my-tooltip" rel="tooltip" href="#" data-original-title="CPR + O<sub>2</sub>.">First-Aid</a>
But it will just show CPR + 0<sub>2</sub>
in the tooltip when I hover over it.
Can't it be done, or am I doing something wrong?
Add the attribute
data-html="true"
