title: Remove outline on antd select component
body: <p>I'm using antd NPM package's Select component. I want to remove the blue outline which appears when the component is focussed. How can I remove it ?</p>
  
  <p>I have tried styling the component using styled components. The styling looks like follows:</p>
  
  <pre><code>const StyledSelect = styled(Select)`
  
      &amp; .ant-select-selection__rendered {
          width: 200px;
          margin-left: 0;
          margin-right: 0;
          &amp;:focus {
            outline: none;
            border: none;
          }
      }
      &amp;.ant-select-focused {
        border: none;
        &amp;:focus{
          outline: 0;
        }
      }
  `;
  </code></pre>
  
  <p>I expect the blue outline to be removed. But my styling doesn't seem to be working</p>
