Do-do-do-do-do Well, you must be a girl with shoes like that She said, you know me well...

Install

Install package via npm

npm install chelsea-dragger

Import it to your script with import or require and add it to your vue app via use() method of your app instance:

import ChelseaDragger from 'chelsea-dragger'
createApp(App).use(ChelseaDragger).mount('#app')

General Usage

The following example uses the array of items shown below.

All items in this array are assigned to one of two lists by property listId. The examples will implement draga and drop to update the an items listId by dragging the item and dropping it in the new list.

Important: Keep in mind that vue needs a unique key in a loop, if the items may change. For this reason all items have a unique id.

const items = [
  {
    id: 1,
    title: 'Some Item',
    listId: 1,
  },
  {
    id: 2,
    title: 'Another Item',
    listId: 2,
  },
  {
    id: 3,
    title: 'Also an Item',
    listId: 2,
  },
  {
    id: 4,
    title: 'One more Item',
    listId: 1,
  },
  {
    id: 5,
    title: 'Okay still one more...',
    listId: 1,
  },
]

Drag

To register an element as draggable, use the directive v-draggable. This directive requires a value, that is passed as a reference to your callback function and drop event, when dropped in a drop zone.

      <div
         v-for="item in items.filter(item => item.listId === 1)"
         :key="item.id"
         v-draggable="item"
      >
        {{ item.title }}
      </div>

Drop

To define an area, where items can be dropped, use The DropZone component. You can just wrap it around any other elements, to mark this area as drop zone.

When an item is dropped, the drop zone will emit a drop event and invoke an optional callback property. In both cases one argument is passed, which is a reference to the value that was passed when registering a draggable element via v-directive.

The example below shows two lists that update the items listId. The first list uses the callback property, the second one the drop-event.

    <DropZone :callback="(item) => (item.listId = 1)">
      <div
        v-draggable="item"
        v-for="item in items.filter(item => item.listId === 1)"
        :key="item.id"
      >
        {{ item.title }}
      </div>
    </DropZone>

    <DropZone @drop="(item) => (item.listId = 2)">
      <div
        v-draggable="item"
        v-for="item in items.filter(item => item.listId === 2)"
        :key="item.id"
      >
        {{ item.title }}
      </div>
    </DropZone>
