title: How to change initialValue dynamically inside getfielddecorator antd?
body: <p>I want to change initial value of select when ever user selects option.</p>
  
  <p>To be more precise, I have many options to select and by default I want display "All" and whenever user selects another option(s) "All" option should disappear.</p>
  
  <p>What I have done : I have tried to render initialValue conitionally whenever user selects option</p>
  
  <pre><code>      &lt;Form.Item label="Компьютеры"&gt;
          {getFieldDecorator("computers", {
            initialValue: this.props.status ? null : "All",
  
          })(
            &lt;Select
              mode="multiple"
              onChange={this.handleCompChange}
            &gt;
              {this.props.comps.map(comp =&gt; (
                &lt;Option value={comp.key} key={comp.key}&gt;
                  {comp.name}
                &lt;/Option&gt;
              ))}
            &lt;/Select&gt;
          )}
        &lt;/Form.Item&gt;
  </code></pre>
