Tree with Multi Selection

The default selection (when clicking on the Tree's title) is one node selection only, Tree supports multi selection by setting the multi-selection property on the \{{em-tree}} tag to true, this mode will render a checkbox near every node in the tree, letting the user select or de-select every node.

Demo

{{em-tree model=model selected=current expand-depth=expandDepth in-multi-selection=true multi-selection=multi}}

\{{em-tree model=model selected=current expand-depth=expandDepth}}

Total #{{multi.length}} selected items: {{multiNames}}

Code

Ember.Controller.extend
    expandDepth: 0
    actions:
        anotherLevel: ->
            @set 'expandDepth', @get('expandDepth')+1
