How do I install Collapsible Sidebar?

Run npx shadcn@latest add @aceternity/collapsible-sidebar in your terminal. Before installing, add the Aceternity Pro registry to your components.json and set your API token as the ACETERNITY_PRO_TOKEN environment variable. The CLI automatically installs all required dependencies including Tailwind CSS plugins and Framer Motion.

Is Collapsible Sidebar responsive and accessible?

Yes. The component is fully responsive across mobile, tablet, and desktop breakpoints. It uses semantic HTML elements, proper heading hierarchy, and accessible color contrast ratios. Touch targets are appropriately sized for mobile interactions, and all interactive elements are keyboard-navigable.

Can I customize the colors, fonts, and layout?

Everything is built with Tailwind CSS utility classes and Framer Motion animations. You can change colors, spacing, typography, border radius, shadows, and animation timing directly in the JSX — no separate CSS files to manage. The component uses your project's Tailwind theme, so it automatically adapts to your design system.

What frameworks does this work with?

Collapsible Sidebar is built for React and Next.js (App Router and Pages Router). It requires Tailwind CSS v4 and Framer Motion. It works with any React-based framework including Remix, Gatsby, and Vite — just ensure Tailwind CSS and Framer Motion are configured in your project.

Collapsible Sidebar

A sidebar with a toggle button to expand and collapse. Maintains state between interactions and includes a smooth width transition.

Unlike the hover sidebar, this version uses an explicit toggle button (arrow icon) to control open/close state. The state is stored in useState and persists until the user clicks the toggle again.

When collapsed, the sidebar shows only icons. When expanded, icons and labels display side by side. The Framer Motion animate prop smoothly transitions the width between collapsed (60px) and expanded (200px) states.

The sidebar uses React Context to share open state with child components. Links can check this context to determine whether to show labels. A SidebarLink component handles the conditional rendering.

Works well for applications where users prefer manual control over sidebar visibility, complex dashboards, or anywhere persistent sidebar state improves the user experience.
