title: Material UI List - Separate OnClick for Expand
body: <p>I have a <code>material ui</code> list that has a nested list. I was wondering if I could have separate <code>onClick</code> handlers for when someone clicks anywhere on the list item and for when they specifically click on the expand icon (the upside-down carrot icon on the right side of the list item).</p>
  
  <p>Basically, I want a default procedure to happen when they click anywhere on the list item aside from the carrot icon, and then a separate procedure for when they try to expand the nested list.</p>
  
  <p>Is this possible?</p>
  
  <p>Note: I'm using <code>ReactJs</code></p>
