title: Add custom attribute on Joomla menus
body: <p>im triying to add an attribute to a item on Joomla menu but fail.</p>
  
  <p>Im designin a site that is like "one page" with Warp Framework and the uikit has a smooth scroll option. Im just have to add "data-uk-smooth-scroll" on the link as a attribute</p>
  
  <p>My menu has some items that links to anchors but i want them to feel smooth.</p>
  
  <p>In other forums i read that i can do it using Jquery to add to all href that start with #, the code i use and fail in this </p>
  
  <pre><code>    $('a[href*=#]').prop('data-uk-smooth-scroll');
  </code></pre>
  
  <p>Is this the way or is a way to do it inside the joomla menu options. </p>
  
  <p>Greetings (and sorry for my terrific english)</p>
