There's an element you'll find in almost every website or web application in one way or another. And that's the Drop Down effect or "element", usually sharing its name with the HTML select element, also known as select tag or select box.

The select element is an HTML tag that allows us to select one or multiple options, usually in forms.

While the Drop Down effect or "element" can also make reference to the visual effect that allows us to navigate submenus in headers, sidebars, or other menu-kind of elements.

In this article, we'll be focusing on both. These are simple and easy to integrate into your design, with pure HTML, CSS and some JavaScript.
