title: How can I change a scroll wheel Picker menu to a drop down menu in React Native with Expo?
body: <p>I am trying to create a drop down menu using Expo and React-native-picker.</p>
  <pre class="lang-js prettyprint-override"><code>                 &lt;TouchableOpacity style={styles.pickerContainer}&gt;
                      &lt;Picker 
                          selectedValue={selectedProduct}
                          style={styles.pickerStyle}
                          itemStyle={styles.pickerItemStyle}
                          onValueChange={(value, key) =&gt; {
                              setSelectedProduct(value)
                          }}
                          
                          
                      &gt;   
                          {getProductOptions(products)}
                      &lt;/Picker&gt;
                  &lt;/TouchableOpacity&gt; 
  </code></pre>
  <p>When I run <code>expo start</code> the drop down menu appears just as I want. However, when I open it in iOS simulator, I get a scroll wheel. Is there a some prop that needs to be changed to get the drop down menu in iOS?</p>
