CopyToClipboard is a simple wrapping component, it does not render any tags, so it requires the only child element to be present, which will be used to capture clicks.

<CopyToClipboard text="Hello!">
  <button>Copy text to clipboard</button>
</CopyToClipboard>

<CopyToClipboard text="Hello, <b>I am bold</b>!" options={{asHtml: true}} >
  <button>Copy html to clipboard</button>
</CopyToClipboard>
