debugged the code I think it will be this function onSelect

问题

• I had working code in react class
• but when I changed to React.Component the whole UI is breaking.
• debugged the code I think problem will be this function onSelect.
• since if I give console statements its not printing anything.
• can you tell me how to fix it.

• i even checked the css it is same.

  providing code below

class Accordion extends React.Component {
  constructor(props) {
    super(props);

I've created a working solution here: JSFiddle

It seems that React.cloneElement prepends a modifier onto the props that are assigned. So instead of having a prop "_onSelect", it is being prepended by "$Accordion"

A working function call on those props looks like this:

this.props.$Accordion_onSelect(this.props.id);    

To remove the $Accordion addition, don't start the prop key with an underscore. If it's just 'onSelect' then it will be passed as 'onSelect'. Here's the JSFIddle
