This ember-cli addon provides a component that allows for 'tethering' a block to a target somewhere else on the page. The target may be an element, an element selector, or an Ember view. Importantly, the component retains typical context for Ember action handling and data binding.
ember-tether is currently tested in Ember 2.4 and higher. For support for earlier versions of Ember, use ember-tether 0.3.1.

ember install ember-tether
Note: Ember CLI versions < 0.2.3 should use ember install:addon
instead of ember install
Given the following DOM:
<body class="ember-application">
<div id="a-nice-person">
Nice person
</div>
<div class="ember-view">
<!-- rest of your Ember app's DOM... -->
</div>
</body>
and a template like this:
Then "A puppy" would be rendered alongside the a-nice-person
div.
If the ember-tether component is destroyed, its far-off content is destroyed too. For example, given:
If isShowing
starts off true and becomes false, then the "A puppy" text will be removed from the page.
Similarly, if you use ember-tether
in a route's template, it will
render its content next to the target element when the route is entered
and remove it when the route is exited.
Hubspot Tether works by appending tethered elements to the <body>
tag. Unfortunately, this moves your content outside of the Ember application rootElement
during acceptance testing. This breaks event dispatch and action handling, including traditional Ember test helpers like click
.
As of version 1.4.0, we can configure a different element to be used instead of body. This can be useful for Ember tests.
// config/environment.js
ENV['ember-tether'] = {
bodyElementId: 'ember-testing'
};
It is also possible to pass a bodyElement
to a particular ember-tether component declaration.
