title: How to add an aria attribute to a styled component?
body: <p>I am using the <code>styled-components</code> npm package and need to add the <code>aria-haspopup</code> attribute to my extended Button component. I have tried the following, but this doesn't add the attribute:</p>
  
  <pre><code>import Button from './button';
  
  const StyledBtn = Button.attrs({
      'aria-haspopup': 'true',
  }).extend``;
  </code></pre>
