title: React Native Select List Population
body: <p>I am using this React Native package: <a href="https://github.com/gcanti/tcomb-form-native" rel="nofollow noreferrer">https://github.com/gcanti/tcomb-form-native</a> for display and capture form inputs.</p>
  
  <p>And I got questions on display the select list based on custom API response.</p>
  
  <pre><code>{
      "response": {
      "countries": [
        {
          "PK_country_id": 132,
          "country_code": "MY",
          "country_name": "Malaysia"
        },
        {
          "PK_country_id": 196,
          "country_code": "SG",
          "country_name": "Singapore"
        },
        {
          "PK_country_id": 32,
          "country_code": "BN",
          "country_name": "Brunei"
        },
        {
          "PK_country_id": 36,
          "country_code": "KH",
          "country_name": "Cambodia"
        }
      ]
    }
  }
  </code></pre>
  
  <p>Well, the documentation did mentioned populating the select list based on enums</p>
  
  <pre><code>const Country = t.enums({
    'IT': 'Italy',
    'US': 'United States'
  }, 'Country');
  </code></pre>
  
  <p>Any guidance for transforming the custom API response into the enums format provided? Please correct me if I am wrong.</p>
