title: Is there a way to use Material-UI Collapse and Drawer without Transition?
body: <p>I'm using Collapse and Drawer from <a href="https://material-ui-next.com/" rel="nofollow noreferrer"><code>material-ui</code> v1 beta</a> to create navigation on mobile website. The navigation has many <a href="https://material-ui-next.com/demos/lists/#nested-list" rel="nofollow noreferrer">nested lists</a>.</p>
  
  <p>When I click to expand/collapse a Collapse, there is noticeable delay until the Collapse start to animate. The same problem also occur on the Drawer.</p>
  
  <p>Both Collapse and Drawer use Transition for animation. Transition is provided by <code>react-transition-group</code>.</p>
  
  <p>To improve responsiveness, I plan to use Collapse and Drawer without Transition (I don't mind having no animation). Is there a way to use Collapse and Drawer without Transition?</p>
  
  <p>P.S. I've checked Collapse's and Drawer's documentation and don't find prop or flag to disable Transition.</p>
