Although Ionic has many out-of-the-box components, you may want to start customizing the existing components or create your own. There are many scenarios where you just cannot fit the default components in your specific use cases. Here are some of the examples of the scenarios:
Custom input fields
The formatting of data with your specific requirements
The binding of your own UI component with Ionic events
The creation of animation based on stateful events
