title: How to retrieve the key into a Semantic-ui-react dropdown?
body: <p>I have small question about react dropdown menus. </p>
  
  <p>I can extract the values inside the dropdown, but I also need the key, because my page is for selling stuff. So, it is an associative table and I need the id from each table to make my query <strong>INNERJOIN</strong>.</p>
  
  <p>This is how I fill it: </p>
  
  <pre><code>let options_customers = [];
  
  serviceList[0].map((service, i) =&gt;
                      options_customers.push({ 
                          key: service.Id, 
                          text: service.Name, 
                          value: service.Name 
                       })) 
  </code></pre>
  
  <p>My dropdown:</p>
  
  <pre><code>  &lt;Dropdown 
      selection options={options_customers} 
      onChange={this.handleChange} 
      value={value} key={options_customers.key} 
      name="selectCustomer" placeholder='Select Customer' 
    /&gt;
  </code></pre>
