interface FormInputComponent<C = InputComponentConfig> {
  isListInput?: boolean;
  readonly: boolean;
  formControl: FormControl;
  config: C;
}

Should be set to true if this component is designed to handle lists. If true then the formControl value will be an array of all the values in the list.

This is set by the Admin UI when consuming this component, indicating that the component should be rendered in a read-only state.

This controls the actual value of the form item. The current value is available as this.formControl.value, and an Observable stream of value changes is available as this.formControl.valueChanges. To update the value, use .setValue(val) and then .markAsDirty().

Full documentation can be found in the Angular docs.

The config property contains the full configuration object of the custom field or configurable argument.
