- *
- * @name ShowWhen
- * @description
- * The `showWhen` attribute takes a string that represents a platform or screen orientation.
- * The element the attribute is added to will only be shown when that platform or screen orientation is active.
- *
- * Complements the [hideWhen attribute](../HideWhen). If the `showWhen` attribute is used on an
- * element that also has the `hideWhen` attribute, the element will not show if `hideWhen` evaluates
- * to `true` or `showWhen` evaluates to `false`. If the `hidden` attribute is also added, the element
- * will not show if `hidden` evaluates to `true`.
- *
- * View the [Platform API docs](../../../platform/Platform) for more information on the different
- * platforms you can use.
- *
- * @usage
- * ```html
- * <div showWhen="android">
- * I am visible on Android!
- * </div>
- *
- * <div showWhen="ios">
- * I am visible on iOS!
