ember-elsewhere

This addon makes it easy to manage sidebars, toolbars, popups, modals, or any piece of DOM that you want to lift outside your normal route hiearchy.

It is similar to ember-wormhole, but is a better choice when your target is within your own Ember app (as opposed to arbitrary, potentially foreign DOM). It is also easier to compose with animations and it's based on 100% public API.

The best documentation is the sample application in tests/dummy, which is also running at http://ef4.github.io/ember-elsewhere/.

Install

ember install ember-elsewhere

Components

Create a target named "my-right-sidebar":

{{from-elsewhere name="my-right-sidebar"}}

Anywhere else in your app, declare which component should render in the target -- complete with bound inputs and actions:

{{to-elsewhere named="my-right-sidebar" send=(component "cool-thing" model=model launch=(action "launchIt"))}}

For fancier behaviors, you can use the block form of {{#from-elsewhere}}, which gives you an opportunity to extend the target's behavior in arbitrary ways. For example, this lets your target animate as its content changes:

{{#from-elsewhere name="modal" as |modal|}}
  {{#liquid-bind modal as |currentModal|}}
    <div class="modal-background"></div>
    <div class="modal-container">
      {{component modal}}
    </div>
  {{/liquid-bind}}
{{/from-elsewhere}}

Rendering multiple components into a single target

There might be use cases where you would like to render multiple component into a single target, for example a from-elsewhere "actions" might receive multiple action buttons via to-elsewhere. Instead of from-elsewhere just use the complementary multiple-from-elsewhere component.

{{multiple-from-elsewhere name="actions"}}
<!-- ... -->
{{to-elsewhere named="actions" send=(component "test-button" text="Button1")}}
{{to-elsewhere named="actions" send=(component "test-button" text="Button3")}}
{{to-elsewhere named="actions" send=(component "test-button" text="Button2")}}

Passing additional state through to the target

When you're using the block form of from-elsewhere, it's entirely up to you what value you send to the target. It can be more than just a component. Here is a complete example of an animatable modal that supports an onOutsideClick action while providing shared layout for the background and container:

{{to-elsewhere named="modal"
               send=(hash body=(component "warning-message")
                          onOutsideClick=(action "close")) }}

{{#from-elsewhere name="modal" as |modal|}}
  {{#liquid-bind modal as |currentModal|}}
    <div class="modal-container">
      <div class="modal-background" onclick={{action currentModal.onOutsideClick}}></div>
      <div class="modal-dialog" >
        {{component currentModal.body}}
      </div>
    </div>
  {{/liquid-bind}}
{{/from-elsewhere}}
