title: Want to close the sidepanel using the minus icon
body: <p>Currently the sidepanel opens using PLUS symbol and is closed using the close btn on the sidepanel.
  PLUS symbol now changes to minus but it doesn't go back to plus when the sidepanel is closed and also I want to be able to click the minus symbol and close the sidepanel as well.</p>
  
  <p>Hope I made my point clear.
  Here is the jsfiddle related to it:
