  An item from the Spree Taxonomies side bar component.

  **To Override:** You'll need to run the components generator:

  ```bash
  ember g spree-ember-storefront-components
  ```

  This will install all of the Spree Ember Storefront component files into your
  host application at `app/components/spree-*.js`, ready to be extended or
  overriden.
