In order for the phone input field to render correctly with flags and dropdown styles, you need to include the required CSS file in your angular.json:

• Open your angular.json file.
• Add the intl-tel-input styles to the styles array in angular.json:

{
  "projects": {
    "your-app": {
      "architect": {
        "build": {
          "options": {
            "styles": [
              "src/styles.css",
              "node_modules/intl-tel-input/build/css/intlTelInput.css"
            ]
          }
        }
      }
    }
  }
}

ngxPhoneField directive returns the full intl-tel-input instance when the input changes. This gives the access to all the methods and properties available in the intl-tel-input API, providing full flexibility for advanced use cases.

You can pass various options to configure the behavior of the phone input field through ngxPhoneFieldParams. The ngxPhoneFieldParams input accepts a configuration object, which includes all the properties from intl-tel-input. You can refer to the full list of properties in the Initialisation Options section here or see them below: .

Once you initialize the ngxPhoneField, the directive returns an instance of intl-tel-input with the following methods and properties:

Enabling formatting and validation for phone numbers requires the utils.js script. Make sure to include this in your project to fully enable these features. For more information, you can refer to the official documentation - Loading The Utilities Script section.
