This plugin targets menus anchors. Then when any gets clicked, this plugin makes the document scroll smoothly to the targeted element.
It is using a native Javascript function that works in many browsers. Note that some browsers will not display the scrolling smooth animation and only point the targeted element without animating the scrolling.

This plugin adds a smooth scroll effect motion to anchor links on the same page. 
You can apply the effect to all posts/pages or certain posts/pages and adjust scroll speed.
The links are bound by the id attribute.
For the source/origin element, link to the target like so, with a href attribute of the target id <code><a href="#example"></a></code>
For the target element, you give it a corresponding id attribute like so – <code><h2 id="example">the target</h2></code>
