Overview

The Elastic Collapsible Sidebar component is a UI component in Lerpa UI's 1318-item shadcn-compatible registry, built for React 19 and Tailwind CSS v4. It works out of the box with no required props. It builds on framer-motion, lucide-react. Install it once with the CLI and the source is written into your project as a file you own — read it, edit it, or remove it, with no version to lock.

Install options

Add Elastic Collapsible Sidebar with the Lerpa CLI, or with the shadcn CLI pointed at the registry URL — the source is shadcn-compatible, so either tool writes the same file.

# Lerpa CLI
pnpm dlx lerpa-cli add elastic-collapsible-sidebar

# shadcn-compatible
npx shadcn add https://lerpaui.com/r/elastic-collapsible-sidebar.json
