Tether an element to another element in the DOM
npm install ember-tetherThis 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.js v3.28 or above
* Ember CLI v3.28 or above
* Node.js v14 or above
For Ember 1.13 - 2.3, use 0.4.1. For support for earlier versions of Ember, use ember-tether 0.3.1.

Given the following DOM:
``html`
Nice person
and a template like this:
`hbs`
@targetAttachment='top right'
@attachment='top left'
>
A puppy
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:
`hbs`
{{#if this.isShowing}}
@targetAttachment='top right'
@attachment='top left'
>
A puppy
{{/if}}
If this.isShowing starts off true and becomes false, then the "A puppy" text will be removed from the page.
Similarly, if you use 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.
Tether works by appending tethered elements to the
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 0.4.0, we can configure a different element to be used instead of body. This can be useful for Ember tests.
`js
// config/environment.jsENV['ember-tether'] = {
bodyElementId: 'ember-testing'
};
`It is also possible to pass a
