If the parent is the enclosing component, and the child component is rendered through the parent’s `{{yield}}` helper, then the child should have access to properties in the parent component via `parentView`. There’s an [outstanding proposal](http://discuss.emberjs.com/t/isolation-of-components-always-required/5036) to rename this to `parentComponent` for components.

Allow the parent template to wrap the child components:

```nohighlight
<script type="text/x-handlebars" id="components/filter-options">
      <h2>{{input type="checkbox" checked=hasSelectAll}} Filter Options</h2>
      {{yield}}
</script>

```

Then make use of the templates like this:

```nohighlight
{{#filter-options}}
     {{filter-option ...}}
     {{filter-option ...}}
{{/filter-options}}

```

And then in the child controller:

```auto
parentHasSelectAll: Ember.computed.oneWay('parentView.hasSelectAll')

```
