/**
 * @name Item
 * @description
 * Creates a list-item that can easily be swiped, deleted, reordered, edited, and more.
 *
 * There are three common ways to use an item:
 * - Use `<ion-item>` for something that is only non-clickable text.
 * - Use `<button ion-item>` for something that can be clicked/tapped. Typically this element will also have a `(click)` handler.
 * - Use `<a ion-item>` for when the item needs to contain a `href`.
 *
 * By default, `<button ion-item>` and `<a ion-item>` will receive a right arrow icon on iOS to signal that tapping the item will reveal more information.
 * To hide this icon, add the `detail-none` attribute to the item (eg: `<button ion-item detail-none>`). To add the icon when it is not displayed by default,
 * add the `detail-push` attribute (eg: `<ion-item detail-push>`).
 *
 *
 * @usage
 * ```html
 *
 * <ion-list>
 *
 *   // default item
 *   <ion-item>
 *     {% raw %}{{item.title}}{% endraw %}
 *   </ion-item>
 *
 * </ion-list>
 *
 *  ```
