title: How to add a select custom field to checkout page in WooCommerce?
body: <p>I'm adding extra fields to the checkout page in WooCommerce, 
  I've added basic text fields ok, but I want a dropdown or select box with a few options, 
  Here is what I've done so far but I've made an error somewhere</p>
  
  <pre><code>$fields['billing']['billing_meat'] = array(
      'label'     =&gt; __('Food options', 'woocommerce'),
  'placeholder'   =&gt; _x('', 'placeholder', 'woocommerce'),
  'required'  =&gt; false,
  'clear'     =&gt; false
  'type'  =&gt; 'select',
  
  'options' =&gt; array(                     // array of key =&gt; value pairs for select options
              __('I eat meat', 'woocommerce') =&gt; __('I eat mate', 'woocommerce'),
              __('meat is gross', 'woocommerce') =&gt; __('meat is gross', 'woocommerce'),
  </code></pre>
  
  <p>Maybe I'm not defining 'type' field correctly?</p>
  
  <p>thanks loads</p>
