Navigation - AvSideMenu

✨ Introduction

The AvSideMenu component is a flexible and accessible navigation side-menu that provides a collapsible sidebar container for navigation purposes. It focuses on layout and collapse functionality, allowing you to insert any content via slots while maintaining full accessibility and keyboard navigation support.

Built with Vue 3 and TypeScript, this component offers smooth transitions, responsive design, and optional collapse functionality that can be enabled or disabled as needed. The component uses defineModel for automatic internal state management, working seamlessly both with and without v-model.

🏗️ Structure

The side-menu component consists of the following elements:

• Header (optional): Contains the collapse/expand toggle button when collapsible=true
• Toggle Button (optional): Interactive button to collapse/expand the menu (only when collapsible)
• Content Area: Scrollable area containing your custom content via default slot

The component integrates focus management, proper ARIA attributes, and responsive design patterns for optimal accessibility.

collapsible	boolean	true		Whether the collapsing feature is enabled
width	string	'16rem'		Width of the side-menu when expanded
collapsedWidth	string	'5rem'		Width of the side-menu when collapsed

v-model
