title: Add tool tip description next to product attribute dropdown menu woocommerce
body: <p>I would like to add a tool tip to each product variation dropdown with a small description. Here is a screenshot of what I'm envisioning.</p>
  
  <p><a href="https://i.stack.imgur.com/k5GqH.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/k5GqH.jpg" alt="enter image description here"></a></p>
  
  <p>I thought about using CSS and adding the pseudo element :after, but I can't make it clickable. Also I don't see a hook to add content to each dropdown. </p>
