Ember CLI DnD

About

A ember component to make all elements drag- or dropable

Install

npm install ember-cli-dnd --save-dev

Usage

In a template use the drag-element or drop-element helper

<ul class="list-group">
  {{#each item in items}}
    {{#drag-element item=item.id elementName='something'}}
      <li class="list-group-item drag-element">{{item.name}}</li>
    {{/drag-element}}
  {{/each}}
</ul>
{{#drop-element dropAction='dropDelete' elementName='trash'}}
  <div> class="list-group-item list-group-item-danger">Trash</div>
{{/drop-element}}

In the controller for the template you must create an action that matches the name given in the helper.

Ember.Controller.extend({
  actions: {
    dropDelete: function(item, elemetName, senderElement) {
      ...
    }
  }
});

Make special note of this.set('savePromise', promise); In order for async-button to work correctly the promise in the action must be assigned to the property of <actionName>Promise. So if you are using an action named destroyRecord you need to assign to destroyRecordPromise.

Options drag-element

item

This is the value to transfer to the drop-element, it can be a single value or a object. Do not tranfer ember-data objects cause they do not serialize properly.

elementName

This is a optional information to inform the drop-element where the information comes from.

Options drop-element

dropAction

Provide the action name that should be called when a element is dropend onto. The action handler gets the item item, element where its got droped onto elemetName and the element where it's coming from senderElement

elementName

This is a optional information to inform the drop-element where the information comes from.
