Navigation

The navigation component is used inside the header to navigate back and forth according to the navigational history array, which is created by the application. By clicking a horizontally-listed element on the navigation, you can move to the target page.

Default Selector

Make the navigation component with the class="ui-navigation" or data-role="navigation" attribute. For semantic understanding, use the nav element.

<div class="ui-page">
   <div class="ui-header" data-position="fixed">
      <h1>title</h1>
      <nav class="ui-navigation" id="navigation"></nav>
   </div>
   <div class="ui-content"></div>
</div>
