I am trying to use the Bootstrap tooltip in an app of mine. Currently, I have the following:

<!-- language: lang-html -->

<button type="button" class="btn btn-default" 
        data-toggle="tooltip" data-placement="left"
        title="Tooltip on left">
            Tooltip on left
</button>

Unfortunately, my tooltip is not showing. I'm trying to figure out what I'm doing wrong. I know that it can be created via JavaScript. However, I'm trying to define my tooltip declaratively. I've confirmed that the Tooltip.js file is being included. However, I can't figure out what I'm doing wrong.

Is it possible to use a tooltip in a pure declarative sense? If so, can someone show me how via a JSFiddle or Bootply sample? I'm really banging my head on this one.

No, it is not possible to use the tooltip in a pure declarative sense. From the Docs:

Opt-in functionality:
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

So you must call .tooltip() manually in JavaScript like this:

<!-- language: lang-js -->

$("[data-toggle=tooltip]").tooltip();

Or use whatever selector you want.

Working Demo in jsFiddle

Which should look like this:
