title: Dynamically Open and Close antd / react Collapse Component
body: <p>I want to dynamically open/close Collapse Elements independent of user interaction (to reveal a specific panel via a search result). </p>
  
  <p>The Collapse react component has setActiveKey (and uses it on user click) but it is not exposed to the Collapse Node reference.</p>
  
  <p>Is there anyway to open or close in a way that will not trigger a re-render?</p>
  
  <p>I tried using state and props, but this always re-renders the full tree of nested Collapse components, which in my case takes over 3 seconds. </p>
  
  <p>Posting the full code would be excessive here as there are many interdependent components nested. However the basic structure is visible here: <a href="https://codesandbox.io/s/nk64q4xy8p" rel="noreferrer">https://codesandbox.io/s/nk64q4xy8p</a></p>
  
  <p>I want to open a specific panel via a different user interaction. In the codepen that would be onChange of the select or clicking the button.</p>
