Hello,
Sorry for making you confuse.
To make the menu scroll to sections with animation when you click to it, just 1 condition you have to follow: enter the link of menu item in this format: your_domain + #section_id
Eg:
Your site is: http://website.com
Section ID is: section-services
Your menu link will be: http://website.com/#section-services
