 ## Overview
 
-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](https://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/).

They're toggled by clicking, not by hovering; this is [an intentional design decision](https://markdotto.com/blog/bootstrap-explained-dropdowns/).
 
 Dropdowns are built on a third party library, [Popper](https://popper.js.org/docs/v2/), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js]({{< param "cdn.popper" >}}) before Bootstrap's JavaScript or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper. Popper isn't used to position dropdowns in navbars though as dynamic positioning isn't required.
