title: Toggle "RNPickerSelect" on "onPress" not working
body: <p>So I've been looking for a dropdown picker to be toggled on &quot;on Press&quot; since yesterday yet I found nothing, all I want is to put an icon in a &quot;touchable Opacity&quot;, and when pressed the dropdown picker shows.
  I've been advised to use &quot;react-native-picker-select&quot; library, I imported it and added the usage advised by the library like this</p>
  <pre><code>const Dropdown = () =&gt; {
       return (
           &lt;RNPickerSelect
               onValueChange={(value) =&gt; console.log(value)}
               items={[
                   { label: 'Football', value: 'football' },
                   { label: 'Baseball', value: 'baseball' },
                   { label: 'Hockey', value: 'hockey' },
               ]}
           /&gt;
       ); };
  </code></pre>
  <p>then I called it from the &quot;on Press&quot; but its showing nothing, so what am I missing?</p>
