vue-nestable-keyprop-identifier v2.4.6

This is a fork of vue-nestable

• Why: It is using the configured keyProp as the actual vue key

vue-nestable

Drag & drop hierarchical list made as a vue component.

Goals

• A simple vue component to create a draggable list to customizable items
• Reorder items by dragging them above another item
• Intuitively nest items by dragging right
• Fully customizable, ships with no CSS
• Everything is configurable: item identifier, max nesting level, threshold for nesting

Installation

Install the plugin:

npm install --save vue-nestable

Use the plugin in your app:

import Vue from 'vue'
import VueNestable from 'vue-nestable'

Vue.use(VueNestable)

You can also import the components on-demand, if you wish to do so:

import { VueNestable, VueNestableHandle } from 'vue-nestable'

export default {
  components: {
    VueNestable,
    VueNestableHandle
  }
  ...
}

Example

You only need two components: vue-nestable which renders the list and vue-nestable-handle which indicates the area the user can drag the item by.

Important Note: Each item must have a unique id property and it must be a valid css class name. It can not contain a :, ,, ., ; or other special characters that are invalid in a css class name.

<template>

  <vue-nestable v-model="nestableItems">
    <vue-nestable-handle
      slot-scope="{ item }"
      :item="item">
      {{ item.text }}
    </vue-nestable-handle>
  </vue-nestable>

</template>

<script type="text/babel">
export default {
  data () {
    return {
      nestableItems: [
        {
          id: 0,
          text: 'Andy'
        }, {
          id: 1,
          text: 'Harry',
          children: [{
            id: 2,
            text: 'David'
          }]
        }, {
          id: 3,
          text: 'Lisa'
        }
      ]
    }
  }
}
</script>

Styling

By default, vue-nestable comes without any styling. Which means you can customize the appearance completely to your needs. However, if you want you can take a look at the style used in the demo: example/assets/vue-nestable.css

Props

The following props can be passed to the <VueNestable> Component:

Slots

The <VueNestable> Component has two slots that can be used to render items and a placeholder. See Example for an example on how to use them.

Events

Events are triggered when an item was moved or when a drag operation was completed. When you use v-model to bind your data, the @input event will automatically be handled.

Hooks

Hooks allow you to get finer controll over which items can be moved or take action when a specific item is moved.

Hooks are passed as an Object to the :hooks prop. The object defines a key with the hook name and a function that will be called when the hook fires.

{
  'beforeMove': this.myHookFunction
}

Look here of an example on how to prevent one item from being moved.
