- * @name Input
- * @description
- *
- * `ion-input` is meant for text type inputs only, such as `text`,
- * `password`, `email`, `number`, `search`, `tel`, and `url`. Ionic
- * still uses an actual `<input type="text">` HTML element within the
- * component, however, with Ionic wrapping the native HTML input
- * element it's better able to handle the user experience and
- * interactivity.
- *
- * Similarly, `<ion-textarea>` should be used in place of `<textarea>`.
- *
- * An `ion-input` is **not** used for non-text type inputs, such as a
- * `checkbox`, `radio`, `toggle`, `range`, `select`, etc.
- *
- * Along with the blur/focus events, `input` support all standard text input
- * events like `keyup`, `keydown`, `keypress`, `input`,etc. Any standard event
- * can be attached and will function as expected.
- *
- * @usage
- * ```html
- * <ion-list>
- * <ion-item>
- * <ion-label color="primary">Inline Label</ion-label>
- * <ion-input placeholder="Text Input"></ion-input>
- * </ion-item>
- *
- * <ion-item>
- * <ion-label color="primary" fixed>Fixed Label</ion-label>
- * <ion-input type="tel" placeholder="Tel Input"></ion-input>
- * </ion-item>
- *
- * <ion-item>
- * <ion-input type="number" placeholder="Number Input with no label"></ion-input>
- * </ion-item>
- *
- * <ion-item>
- * <ion-label color="primary" stacked>Stacked Label</ion-label>
- * <ion-input type="email" placeholder="Email Input"></ion-input>

- *
- * <ion-item>
- * <ion-label color="primary" stacked>Stacked Label</ion-label>
- * <ion-input type="password" placeholder="Password Input"></ion-input>

- * @name TextArea
- * @description
- *
- * `ion-textarea` is used for multi-line text inputs. Ionic still
- * uses an actual `<textarea>` HTML element within the component;
- * however, with Ionic wrapping the native HTML text area element, Ionic
- * is able to better handle the user experience and interactivity.
- *
- * Note that `<ion-textarea>` must load its value from the `value` or
- * `[(ngModel)]` attribute. Unlike the native `<textarea>` element,
- * `<ion-textarea>` does not support loading its value from the
- * textarea's inner content.
- *
- * When requiring only a single-line text input, we recommend using
- * `<ion-input>` instead.
- *
- * @usage
- * ```html
- * <ion-item>
- * <ion-label>Comments</ion-label>
- * <ion-textarea></ion-textarea>
- * </ion-item>
- *
- * <ion-item>
- * <ion-label stacked>Message</ion-label>
- * <ion-textarea [(ngModel)]="msg"></ion-textarea>
- * </ion-item>
- *
- * <ion-item>
- * <ion-label floating>Description</ion-label>
- * <ion-textarea></ion-textarea>
- * </ion-item>
- *
- * <ion-item>
- * <ion-label>Long Description</ion-label>
- * <ion-textarea rows="6" placeholder="enter long description here..."></ion-textarea>
