Introduction

scrollbar.js is a js plugin to make your list scrollable, you can both drag and click the list to make it scroll, when you release the mouse, it can rebounds to the nearest item.

Usage

Add the html for your list, notice that the default class selected is necessary.

<div class="list-wrapper">
  <ul id="picker">
    <li class="selected">Item1</li>
    <li>Item2</li>
    <li>Item3</li>
  </ul>
</div>

Add the style, the list's wrapper should be position: relative and overflow: hidden, also the height should be set otherwise you can not drag the list but click.

.list-wrapper {
  position: relative;
  overflow: hidden;
  height: 42px;
  cursor: -webkit-grab;
}

.list-wrapper ul {
  position: absolute;
  width: 100%;
  display: flex;
  justify-content: space-between;
}

.list-wrapper li {
  color: #2A5561;
  padding: 10px;
}

.list-wrapper ul li.selected {
  color: #448AFF;
}

Add the plugin, specify your selector for the list and callback that will trigger when the spring animation ends.

const scrollbar = require('scrollbar.js');
scrollbar({
  selector: '#picker',
  callback: function (index) {
    // the index of the selected item in the list
    console.log(index);
  }
});

and you will see:
