title: Ant Design - Vertical Group of Checkboxes
body: <p>I am trying to make a column of checkboxes using Ant design. I have tried:</p>
  
  <pre><code> &lt;Checkbox.Group&gt;
            &lt;Checkbox&gt;Hello&lt;/Checkbox&gt;
            &lt;Checkbox&gt;Hello1&lt;/Checkbox&gt;
            &lt;Checkbox&gt;Hello2&lt;/Checkbox&gt;
  &lt;/Checkbox.Group&gt;
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>&lt;CheckboxGroup options={plainOptions} value={this.state.checkedList} onChange={this.onChange} /&gt;
  </code></pre>
  
  <p>However, there does not seem to be an option to make checkboxes appear in a column instead of a row. I know I can use flexbox, but I was hoping Ant design would have a builtin method for making checkboxes appear vertically (in a column) instead of appearing in a horizontal row. </p>
  
  <p>Is there a simple solution for stacking the checkboxes vertically?</p>
