How to implement smooth scrolling in UIKit3?

Question

UIkit

Hello! In UIKit, for smooth scrolling, you need to add the uk-scroll attribute. I can't figure out how to add this attribute to standard menu items. If I create a link on the page (following the example of the Uikit3 documentation), everything works out, but the menu buttons do not. Help me please!

<ul class="uk-navbar-nav" uk-scrollspy-nav="closest: li; scroll: true">
    <li><a href="#a">A</a></li>
    <li><a href="#b">B</a></li>
    <li><a href="#c">C</a></li>
</ul>
