body: <p>I add <a href="https://github.com/alinz/react-native-dropdown" rel="nofollow noreferrer">this </a>plugin 
  and try to draw the Dropdown, it works fine 
  in this way </p>
  
  <pre><code> &lt;View style={{ flex: 1, justifyContent: 'center', alignItems: 'flex-start',alignSelf:'center', backgroundColor:'#ebeef0'}}&gt;
            &lt;Select style={{  alignItems: 'flex-start' }}
              width={250}
              ref="SELECT1"
              optionListRef={this._getOptionList.bind(this)}
              defaultValue="Select One of Option ..."
              onSelect={this._canada.bind(this)}&gt;
              &lt;Option&gt;First&lt;/Option&gt;
              &lt;Option&gt;Second&lt;/Option&gt;
              &lt;Option&gt;Third&lt;/Option&gt;
              &lt;Option&gt;Forth&lt;/Option&gt;
              &lt;Option&gt;Fifth&lt;/Option&gt;
              &lt;Option&gt;Six&lt;/Option&gt;
              &lt;Option&gt;Seven&lt;/Option&gt;
              &lt;Option&gt;Eight&lt;/Option&gt;
              &lt;Option&gt;Ten&lt;/Option&gt;
              &lt;Option&gt;Eleven&lt;/Option&gt;
              &lt;Option&gt;Twelve&lt;/Option&gt;
            &lt;/Select&gt;          
  
            &lt;OptionList ref="OPTIONLIST"/&gt;
        &lt;/View&gt;
  </code></pre>

  as
  <a href="https://i.stack.imgur.com/0KDki.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0KDki.jpg" alt="enter image description here"></a></p>
