Enhance menu component by implementing collapse and expand functionality

• Introduced smooth slide-in and slide-out transitions for the sidebar to improve user experience.
• Added a semi-transparent overlay on mobile devices to focus user attention on the menu and prevent background interactions while the menu is active.
• Adjusted menu positioning to fixed on smaller screens for consistent accessibility and usability.
• Ensured proper pointer event handling to avoid unintended clicks when the menu is collapsed.

This update aims to provide a more flexible and intuitive navigation experience for all users.

Sorry for the late reply.

Thanks for making the changes. It would be great if you could add screenshots of the UI to showcase how your changes look.
