title: How to use format whitelist in QuillJS?
body: <p>I have looked around the <a href="https://quilljs.com/docs/quickstart/" rel="nofollow noreferrer">Quill documentation</a>, GitHub topics, and here in Stack Overflow and I have been unable to find a simple example of using the <a href="https://quilljs.com/docs/formats/" rel="nofollow noreferrer">format</a> attribute. I would like to limit my users so that they can only bold, italicize, underline, and hyperlink text. </p>
  
  <p>From what I understand, this can be achieved with a format whitelist, but I have only been able to find examples regarding custom fonts or other more complex properties.</p>
  
  <p>Thank you for your time!</p>
