Quick intro and examples

Directives

ngx-dnd provides a base set of directives to enable drag-and-drop. By default all children of a ngxDroppable element may be dragged and dropped. Add the ngxDraggable to restrict drag-and-drop to the parent container. In general prefer using the base directives to the help components introduced later.

<div class="ngx-dnd-container" ngxDroppable>
  <div class="ngx-dnd-item" ngxDraggable>Item 1</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 2</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 3</div>
</div>

Give multiple containers the same dropZone name to allow drag-and-drop between these containers.

<div class="ngx-dnd-container" ngxDroppable="example">
  <div class="ngx-dnd-item" ngxDraggable>Item 1a</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 2a</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 3a</div>
</div>
<div class="ngx-dnd-container" ngxDroppable="example">
  <div class="ngx-dnd-item" ngxDraggable>Item 1b</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 2b</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 3b</div>
</div>

ngxDraggable items can be restricted to specific containers:

<div class="ngx-dnd-container" ngxDroppable>
  <div class="ngx-dnd-item" ngxDraggable="['example-target']">Item 1a</div>
  <div class="ngx-dnd-item" ngxDraggable="['example-target']">Item 2a</div>
  <div class="ngx-dnd-item" ngxDraggable="['example-target']">Item 3a</div>
</div>
<div class="ngx-dnd-container" ngxDroppable="example-target">
  <div class="ngx-dnd-item" ngxDraggable>Item 1b</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 2b</div>
  <div class="ngx-dnd-item" ngxDraggable>Item 3b</div>
</div>

Components

ngx-dnd provides a set of helper components that encapsulates the directives mentioned and adds capability for data driven structures. In general you should prefer directives to components.

orderableLists = [
  [
    "Item 1a",
    "Item 2a",
    "Item 3a"
  ],
  [
    "Item 1b",
    "Item 2b",
    "Item 3b"
  ]
]
<ngx-dnd-container
  [model]="orderableLists">
</ngx-dnd-container>

This component is effectively equivalent to:

<div class="ngx-dnd-container" ngxDroppable [model]="orderableLists">
  <div
    class="ngx-dnd-item"
    ngxDraggable
    *ngFor="let item of orderableLists">{{item}}</div>
</div>

Including nested containers:

<ngx-dnd-container
  [model]="nestedLists">
</ngx-dnd-container>
nestedLists = [
  {
    "label": "Item 1",
    "children": []
  },
  {
    "label": "Item 2",
    "children": [
      {
        "label": "Item 2a",
        "children": []
      },
      {
        "label": "Item 2b",
        "children": []
      },
      {
        "label": "Item 2c",
        "children": []
      }
    ]
  },
  {
    "label": "Item 3",
    "children": [
      {
        "label": "Item 3a",
        "children": []
      },
      {
        "label": "Item 3b",
        "children": []
      },
      {
        "label": "Item 3c",
        "children": []
      }
    ]
  }
]

Install

To use ngx-dnd in your project install it via npm:

  • npm i @swimlane/ngx-dnd --save
  • Add NgxDnDModule to your application module
  • If using directives you will need to BYO styles or include @swimlane/ngx-dnd/release/index.css.

  • cd ngx-dnd
  • npm install
  • npm start

CHANGELOG

This project uses heff/chg, a simple changelog/release history manager. When contributing to this project please add change notes (manually or using the heff/chg cli) to the ## HEAD (Unreleased) section.

Release

This project uses sindresorhus/np, a better npm publish. To publish a new version to npm, first ensure all entries in the ## HEAD (Unreleased) section of the changelog are appropriate, commit changes, and push changes to github (if not already done). Then use npm run np to launch an interactive UI that will guide you through publishing a new version. sindresorhus/np and heff/chg will perform various pre-publish checks, run tests, bump the version number, update the changelog, then publish to npm and push to github.

Manual process
  • rm -rf node_modules
  • npm i
  • npm test
  • update version in package.json
  • Update CHANGELOG.md:
    • move entries in the ## HEAD (Unreleased) section below the horizontal rule, under a new header with the version number.
    • ensure all entries are approprate.
    • Leave a single * _(none)_ entry in the ## HEAD (Unreleased) section.
  • git commit -am {VERSION NUMBER}
  • git tag {VERSION NUMBER}
  • git push --tags
  • npm run package
  • npm publish
