scroll-tabs

As of version 1.0.0 this library exposes ES modules. Use an ES module aware transpiler such as Webpack, Rollup or Browserify + babelify to bundle it for the browser.

scroll-tabs

A tiny utility that adds tab scrolling functionality.

How it works

ScrollTabs adds scroll buttons on the left and right side of the tabs container if not all tabs are visible. It also adds a mouse wheel listener on the container.

If either a button is clicked or the mouse wheel is used over the tabs, a 'scroll' event is being fired. This event contains the node elements of the new and old active tab, and the direction in which the tab has changed relative to the old active tab.

How to use

Provide a tab container

var $el = (
  <div>
    <ul class="my-tabs-container">
      <li class="my-tab i-am-active"></li>
      <li class="my-tab"></li>
      <li class="my-tab ignore-me"></li>
    </ul>
  </div>
);

Initialize scrollTabs

var scroller = scrollTabs($el, {
  selectors: {
    tabsContainer: '.my-tabs-container',
    tab: '.my-tab',
    ignore: '.ignore-me',
    active: '.i-am-active'
  }
});

Listen to the scroll event

scroller.on('scroll', function(newActiveNode, oldActiveNode, direction) {
  // activate the new active tab
});

Update scroller

Every time tabs change and or the tab container resizes, update the scroller:

scroller.update();

How to test

npm run test
