+## Disabling Custom HTML Parsing via `innerHTML`
+
+`ion-alert`, `ion-infinite-scroll-content`, `ion-loading`, `ion-refresher-content`, and `ion-toast` accept custom HTML as strings for certain properties. These strings are added to the DOM using `innerHTML` and must be properly sanitized by the developer. Developers can disable this functionality by setting `innerHTMLTemplatesEnabled: false` in the [IonicConfig](../developing/config#ionicconfig). When `innerHTMLTemplatesEnabled` is `false`, the values passed to the affected components will always be interpreted as strings.

 ## Ejecting from the built-in sanitizer
 
 For developers who wish to add complex HTML to components such as `ion-toast`, they will need to eject from the sanitizer that is built into Ionic Framework. Developers can either disable the sanitizer across their entire app or bypass it on a case-by-case basis.
