5 JavaScript Sliding Menus
Add motion and clarity to your UI with these JavaScript sliding menu examples. From classic vertical sidebars to full-screen overlays and smooth push-out transitions, this collection covers a wide variety of implementations that enhance user interaction and responsive design.
Examples

Curtain Transition Navigation Menu
Curtain Transition Navigation Menu implements a lightweight state toggle via a data-nav attribute, shifting the entire <main> view up by 50% to reveal an absolutely-positioned bottom navigation drawer. Dynamic sizing features like clamp() and max() ensure responsive link layouts, while a sharp cubic-bezier(.13, .53, .38, .97) curve coordinates the simultaneous scaling and entry of image-rich navigation elements. While visually fluid, animating massive full-screen wrappers containing large Unsplash media can trigger costly rasterization overhead unless GPU compositing is actively hinted.
See the Pen Curtain Transition Navigation Menu.

Smooth GSAP Slide-Out Sidebar Navigation
This is a full-viewport e-commerce layout featuring a GSAP-powered off-canvas sidebar navigation. It resolves the conflict between showcasing high-density visual content and maintaining a complex navigation structure. The layout hides primary links off-screen, revealing them through a staggered, hardware-accelerated slide sequence only when requested. (Requires: gsap.js, cssruleplugin.js)
See the Pen Smooth GSAP Slide-Out Sidebar Navigation.

Jello Animated Sliding Tab Navigation
This is a Jello Animated Sliding Tab Navigation. It provides top-level categorization and context-aware sub-menus in a single mobile-friendly component. The function is to visually anchor the user’s location within an app while dynamically adapting the global color theme to match the active context.
See the Pen Jello Animated Sliding Tab Navigation.

Responsive Pinned Sidebar Layout with Popover
A modern sidebar utilizing the View Transitions API for theme switching and the CSS popover attribute for efficient responsive handling, all controlled by a Tweakpane interface to live-adjust CSS variables for duration, blur, and translate effects.
