CSS/SCSS Dropdown & Dropup Component – Drop.css

Drop.css is a CSS/SCSS library to create a customizable, animated dropdown or dropup component with plain HTML.

How to use it:

1. Override the default variables in the drop.scss and compile it to drop.css.

$dropArrowOffset: 2px;
$dropArrowRadius: 7px;
$dropMenuBorderRadius: 5px;
$dropMenuPrimaryColor: lighten(#111, 15%);
$dropMenuLighterColor: #bdc3c7;
$dropMenuSecondaryColor: #148a73;
$dropSafeZoneOverlap: 10px;
$dropAnimationSpeedMultiplier: 1;

$sass drop.scss drop.css

2. Load the drop.css in the document or directly import the drop.scss into your project.

<link rel="stylesheet" href="drop.css" />

3. Create a container for the dropdown. Available CSS utilities:
