🌐 Custom Language Support

You can add custom translations or override existing ones using provideCountrySelectConfig().

Adding extra translations (e.g. Polish)

// app.config.ts
import { provideCountrySelectConfig } from '@wlucha/ng-country-select';

export const appConfig: ApplicationConfig = {
  providers: [
    provideCountrySelectConfig({
      extraTranslations: {
        de: { pl: 'Niemcy', ja: 'ドイツ' },
        at: { pl: 'Austria', ja: 'オーストリア' },
        fr: { pl: 'Francja', ja: 'フランス' },
        // ... add translations for all countries
      }
    })
  ]
};

Then use the custom language in your template:

<ng-country-select
  [lang]="'pl'"
  [placeholder]="'Szukaj kraju'"
></ng-country-select>

Replacing the entire country list

For full control, you can replace the built-in country list entirely:

provideCountrySelectConfig({
  countries: [
    {
      alpha2: 'de',
      alpha3: 'deu',
      translations: { en: 'Germany', pl: 'Niemcy', ja: 'ドイツ' }
    },
    // ... your custom list
  ]
})

Exported symbols
