Vue Wheel Picker

Picker is a Vue component that selects a value from the list by dragging the cylinder allowing users to experience the rolling effect.

User can change Picker's value in several ways:

Drag the wheel (supports acceleration)
Use mobile touch moves
Click on the arrows to roll one element up or down
Use mouse wheel or touchpad
Use up or down arrows on the keyboard when the Picker is focused

Since v0.3.0, you can feed huge amount of data to the Picker! Virtualized scroll will take care of the performance.

You can try the Picker with different properties passed to it in the prepared playground: https://picker.vanishmax.com/

Installation

NPM. You can install Picker in different ways. The best one is through NPM:

npm i vue-wheel-picker

Then, import the Picker to your app and use it:

<template>
  <div>
    <Picker :options="years" v-model="currentYear" />
  </div>
</template>

<script>
  import Vue from 'vue'
  import Picker from 'vue-wheel-picker';
  
  function getYears () {
    const currentYear = new Date().getFullYear();
    const years = [];
    
    for (let i = currentYear - 20; i < currentYear + 20; i++) {
      years.push({
        value: i.toString(),
        text: i.toString(),
      });
    }
    
    return years;
  }
  
  export default Vue.extend({
    components: {
      Picker,
    },
    data () {
      const current = (new Date().getFullYear()).toString();
      return {
        years: getYears(),
        currentYear: {
          value: current,
          text: current,
        },
      };
    },
  });
</script>

<style>
  .picker {
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    align-items: center;
    
    max-width: 80%;
    height: 300px;
    margin: 16px auto 0;
    background-color: #F8F8FA;
    border-radius: 4px;
    
    text-align: center;
    font-size: 18px;
    color: #bbbcc9;
  }
  
  .picker_chosen {
    background-color: #F8F8FA;
    border-top: 1px solid #dddde4;
    border-bottom: 1px solid #dddde4;
    color: #121212;
    font-size: 20px;
  }
</style>

Here we've added styles to demonstrate that the Picker carries only most needed styles in itself. It includes 3D styling, positioning and focus handlers, so you need to add only sizes and colors. Therefore, the Picker will surely suit your project!

UNPKG. Alternatively, you can add component to any HTML file via UNPKG:

<!DOCTYPE html>
<html lang="en">
<head>...</head>
<body>
<div id="app">
  <picker />
</div>

<!-- Import Vue and Picker from UNPKG CDN -->
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-wheel-picker"></script>

<!-- Initialize Vue app -->
<script>
  Vue.component('picker', Picker);
  
  new Vue({
    el: '#app',
  })
</script>
</body>
</html>

Properties

Prop name	Type	Default	Description
options	array of value	`[]`	An array of options in format { value: string, text: string } to be displayed in the Picker
value	{ value: string, text: string }	`null`	Default value of the Picker. Use either as initial value or as a v-model
radius	number	`150`	How far is each item in the list from another
perspective	number	`200`	Defines 'how far is the Picker from the viewer'. Visually changes the circless-ness of the Picker
itemHeight	number	`40`	The height of each item in the list. Needed to properly calculate the position of them
sensitivity	number	`8`	How sensible is Picker for touches. The bigger value you put the more acceleration the Picker gains after moving the touch. Must be in the range from 0 to 10.
visibleOptionsAmount	number	`10`	Amount of options that are visible on the ring of a Picker. At maximum, will display passed amount plus one chosen option in the center of the ring. Must be a multiple of 2 for the best experience.
type	'normal' or 'infinite'	`'normal'`	Not supported yet! If 'infinite' is passed, then you can scroll the Picker forever, all values will repeat
arrows	boolean	`false`	Whether the arrows for scrolling to top or to bottom are needed to be displayed

Slots

Name	Props	Description
option	`{ value: string, text: string }`	Slot inside the picker option which allows you to format the texts or add custom data in there
arrow-top		Arrow to roll up. See description below
arrow-bottom		Arrow to roll down

Arrows

There is a built-in support for vertical arrows which pick the next or the previous value in the Picker. To use them, pass the property arrows to the component and add 2 slots like this:

<Picker arrows>
  <template #arrow-top>⟨</template>
  <template #arrow-bottom>⟨</template>
</Picker>

<style>
  .picker_arrow {
    font-size: 18px;
    height: 20px;
    width: 24px;
    padding: 4px;
    margin: 0 auto;
  }
  
  .picker_arrow.top {
    transform: rotate(90deg);
  }
  
  .picker_arrow.bottom {
    transform: rotate(-90deg);
  }
</style>

The flexibility of such approach is that you can put any utf character, or SVG icon or an image there and apply whatever style you like, but the click event is a responsibility of the Picker itself.
