Build hidden sidebars into your project for navigation, shopping carts, and more.

To get started, install Overlay plugin via npm, else you can skip this step if you are already using Preline UI as a package.

                        npm i @preline/overlay


Use the buttons below to show and hide an sidebar element via JavaScript that toggles the .show class on an element with the .hs-overlay class.

  • .hs-overlay.hidden hides content (default)
  • .hs-overlay shows content
