Custom HTML pages are incredibly powerful, they allow you to build almost any type of layout you want. You can fetch API data, add content that works offline, and use Ionic UI components for the layout.
To create a custom page, go to the App Customizer, and click Custom Pages. Below the list of pages, click “Add new page.”
Choose “Custom HTML.”
A form will appear where you can enter your page details. You can add any HTML here, including Ionic UI components and custom API lists (see topics below for more information).
