 Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is [an intentional design decision.](http://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/)
 
-Dropdowns are built on a third party library, [Popper.js](https://popper.js.org), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js](https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.10.1/umd/popper.min.js) before Bootstrap's JavaScript.

 - Popovers require the [tooltip plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/tooltips/) as a dependency.
 - Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
 - Zero-length `title` and `content` values will never show a popover.

 - Tooltips with zero-length titles are never displayed.
 - Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
